StructuralAnalysis (Structural Analysis) Schema
Alias: sa
Version: 1.0.4
Structural Analysis Schema.
StructuralAnalysis schema defines classes that represent data for Structural modeling. Focuses on information that is important in design, construction and modification of the load bearing components of buildings, bridges and other structures.
StructuralAnalysis schema uses topological approach for defining its data: TopologyElements represent base structural model skeleton, other members (beams, slabs) share this data to define their analytical location and connectivity with other elements. Topology elements can be either Private (Path, Wire, Loop, Sheet) or Shared (Vertex, Edge, Face).
Some example applications which will use this schema include: RAM, STAAD, SPPM, Structural Synchronizer.

Behavior specifies that the CurveMember is slightly curved or bent, tipically used with Beams. Positive camber means that the beam is curved upward, this usually provide some extra structural support to a wide span or space by counteracting deflection due to Load. If camber is negative - beam is bent downward, this can indicate a problem either a wear and tear, deterioration or deliberate destructive manipulation to a structure.

Distributed Load which affects a curve. These loads can be both uniform (all points on the curve are affected by same force) and non-uniform (forces that affect each point on the curve vary). CurveLoad can be applied on any curve or surface element (CurveMember, SurfaceMember, CurveSupport, SurfaceSupport).
Two aspects must always be assigned to a CurveLoad:
- RelativeCurveLocationAspect - curve on a host (parent) element where this Load is located.
- CurveLoadValueAspect - defines force (caused by this Load) for the location curve.
CurveLoadValueAspect (Curve Load Value Aspect) Abstract EntityClass
A LoadValueAspect that can be assigned to a CurveLoad.
Base Class: StructuralAnalysis:LoadValueAspect
Inherited properties
| Name | Description | Type | Extended Type |
|---|---|---|---|
| Element | The bis:Element that owns this bis:ElementUniqueAspect | navigation |
Defines an abstract aspect class for setting load values of CurveLoad (e.g. Force). Values along the Curve Load might be both Uniform and Varying.
CurveMember (Curve Member) Sealed EntityClass
Defines a Member that is located along a Path, and whose behavior is defined along that Path.
Base Class: StructuralAnalysis:Member
CurveMember represents a Member that is primarily linear in nature. CurveMember's purpose is to hold the structure by providing resistance from both lateral and gravity loads. Some examples are beams, columns, piles and cables.
CurveMember's analytical location is defined by its child Wire and CurveMemberOwnsLocationWire relationship. CurveMember has a direction which is defined by its location Wire.
CurveMember has local coordinate system (RST):
- RAxis matches direction of CurveMember
- TAxis matches CurveMember's orientation
- SAxis is defined by cross product of TAxis and RAxis
- Origin matches location Wire start point
Connectivity between CurveMember and other elements are defined through Edges and Vertices that are referenced by CurveMember's location Wire. By default all fixities for the CurveMember are treated as fixed. However, these default fixities can be overridden with the aspects:
- VertexReleaseAspect - only used for adjusting fixity for a single specific Vertex
- PathReleaseAspect - only used for adjusting fixity for all Edges that belong to a specific Path. There might be some cases where Edges need to have different fixities in a CurveMember. For this purpose additional sub Wires with CurveMemberOwnsSubWire relationship should be used. Release aspects for sub wires will always override fixity behavior assigned the location Wire. Each Edge referenced by a sub Wire must be referenced by location Wire.
Not all properties of CurveMember are defined in CurveMember class. There are two additional types of properties that can be assigned to a CurveMember:
- Mandatory CurveMember properties, that can be repeated in multiple CurveMembers are grouped by a CurveMemberType, these could include material, thickness, etc
- Optional properties, that define some more unique behavior for that CurveMember that might not exist at all. These behaviors are assigned by MemberBehaviorAspect instances. A single CurveMember might have multiple different type behavior aspects assigned but only one of each kind.

Edge (Edge) Sealed EntityClass
An identified curve location in 3D space.
Base Class: StructuralAnalysis:SharedTopologyElement
Edges provide a curve location (between two Vertices) and connectivity along the curve. Edge has direction from start Vertex to its end Vertex. Edge's location curve cannot self intersect. Edge can refer to the same Vertex for both its start and end.
Edges are only referred to by Paths (through OrientedEdgeAspects). StructuralAnalysisElements that refer to the same Edge are connected. Multiple edges might exist in same location, however elements would not be considered connected if they reference these separate Edges. By default all elements which refer to the same Edge are fixed at its connection curve. Default fixities can be adjusted with these instances:
Any other Element with a relationship to an Edge will not be considered for updating in operations that split, merge or delete the Edge.
Edges are Model-scope shared resources that never have a parent Element.

Faces provide a surface location (bounded by Loops) and connectivity across that surface. Faces are never referenced directly by StructuralAnalysisElements, Surface Elements (SurfaceMembers, SurfaceMemberRegions, SurfaceSupports) can reference Faces through FaceSets.
Faces contain Loops and Wires as children. Loops represent Face boundaries and the Wires represent linear connectivity within the Face. Face always has a single Loop which defines outer boundary. Inner Loops will have opposite normal to outer Loop's. Inner Loops define holes in a Face, two faces would not be considered overlapping if the first face's outer Loop is inside of the other face's inner loop. Faces can also directly refer to Vertices, in case there is another member connected to a Face at a single point - Vertex should be used to define that connection, e.g. Column supporting Slab.
Faces also define surface connectivity by themselves. By default all elements which refer to the same Face are fixed at that spatial surface location. Default fixities can be adjusted with these instances:
Faces are only referred to by FaceSets (through OrientedFaceAspects). Any other Element with relationship to a Face will not be considered in operations that split, merge or delete the Face.
Faces are Model-scope shared resources that never have a parent Element.
Faces can only be planar, however in future Faces might have a Surface property which would allow to define a non-planar surface.

FaceSet is a set of Edge-connected Faces with compatible orientations. Both adjacent Faces must reference Edges that connect them. Edges can never overlap or intersect in a FaceSet.
The Faces of a FaceSet are defined through its ownership of OrientedFaceAspects. A valid FaceSet must always have at least one OrientedFaceAspect.
FaceSet is abstract and only has two subclasses (both sealed):
- Shell (Future) - a closed FaceSet defining the boundary of a Region (future)
- Sheet - an open or closed FaceSet that does not define the boundary of a Region
FaceSets are never shared.

LinearSpringCurveTranslationalBehavior (Linear Spring Curve Translational Behavior) Sealed EntityClass
Linear Spring Curve Translational Behavior.
Base Class: StructuralAnalysis:CurveTranslationalBehavior
Indicates that a CurveSupport has a spring behavior along some specific axis. CurveSupport prevents elements from moving freely along the specified axis. Both CurveSupport and Elements at the connection curve transfer forces between each other, if the direction of that force matches direction along that specified axis. However, unlike FixedCurveTranslationalBehavior, LinearSpringCurveTranslational behavior has a stiffness at the connection which prevents elements from transferring full force through that connection.

Load (Load) Abstract EntityClass
Load which affects analysis members.
Base Class: StructuralAnalysis:StructuralAnalysisElement
Structure loads represent forces, deformations that are applied to StructuralMembers, Supports or Vertices. Properties for load affected elements are calculated by assessing these Loads.
When multiple loads overlap (regardless of the Load Type) the result is always additive.
Loads in StructuralAnalysis schema are always hosted - they always have related Member, Support or Vertex which is assigned through RelativeLocationAspect. Load values are assigned through LoadValueAspect.
StructuralAnalysis provide multiple LoadTypes, all these types could be grouped into a LoadContainer which can be either LoadGroup or LoadCase. LoadCases can reference LoadGroups. Based on Load condition: amount of force produced by the same Load might varry. This variantion is calculated using Load Factors that are defined in a Load Container.
Loads are subclassed by the area they affect:
- PointLoad - affects such a small area that it can be contracted to a single spatial point
- CurveLoad - affects over a curve
- SurfaceLoad - affects over a surface

LoadCombinationInformation (Load Combination) Sealed EntityClass
Element that groups a set of load cases that are applied to the structure simultaneously or sequentially
Base Class: BisCore:InformationRecordElement
A load combination is a set of load cases that are applied to the structure simultaneously or sequentially. A load case is a single type of load, such as dead load, live load, wind load, earthquake load, etc. Load combinations are used to represent different design situations, such as serviceability, strength, stability, or extreme events. For example, a load combination for strength design might include the dead load, the live load, and a fraction of the wind load. A load combination for earthquake design might include the dead load, the live load, and the earthquake load in a specific direction.
Loads and Factors are assigned to LoadCombinationInformations using ([LoadConditionFactors])(#loadconditionfactor).

Represents a major structural component such as: beam, column, wall. Members can transfer forces from one location to another. Members are analytical instances, however they should be modeled to mirror their actual physical locations and sizes as much as practical. “Simplifying” a model by moving Member locations (for example to locate all members on grid lines) is discouraged as these simplified models have little value for drawing production and detailing applications that may utilize the Structural Analysis schema.
Members always have at least one PrivateTopologyElement that defines their location and connectivity to other elements.
There are two types of members in StructuralAnalysisSchema:
- CurveMembers - defined by a Wire
- SurfaceMembers - defined by a Sheet

Path is a sequence of Vertex-connected Edges. Path always has a Parent which uses Path to reference Edges and Vertices to define either a surface or a linear element.
Path is abstract and only has two subclasses (both sealed):
- Loop - a closed Path defining the boundary of a Face
- Wire - an open or closed Path that does not define the boundary of a Face
The Edges of a Path are defined through its ownership of OrientedEdgeAspects. A valid Path must always have at least one OrientedEdgeAspect. Paths can never be shared. Duplicate Paths that reference same Edges and define same connectivity for different members can coexist. Edges in a Path can never intersect.

PrivateTopologyElements always have a parent Element that owns them, if the parent is deleted, the PrivateTopologyElement is deleted also. The parent Element may be a TopologyElement (such as a Face owning Loops) or may be a StructuralElement (such as a CurveMember owning a Wire).
There is one and only one subclass of PrivateTopologyElement for each dimensionality above zero:
- Path for 1D (collection of Edges)
- FaceSet for 2D (collection of Faces)
- Solid (future) for 3D (collection of Regions) (there is no need for a 0D SharedTopologyElement, as there is no strong motivation to manage a collection of Vertices)
Although Private Topology Elements derive from Geometric3dElement, they never have their own graphics. Instead, Private Topology Elements always reference Shared Topology Elements.

Loads are always hosted in Structural Analysis schema. Which means that their location are always relative to the host member. Relative Location Aspect provides base class for defining Load location relative to its host. This gives advantage that the load is always located at same parts of the host, when host is moved or rotated. Each Load host must subclass a mixin that defines properties required for a Load to define its relative location. The mixins are:
- IDefinedPoint - implemented by Vertex and PointSupport
- IDefinedCurve - implemented by CurveMember and CurveSupport
- IDefinedSurface - implemented by SurfaceMember and SurfaceSupport
Each Load subclass has sepperate abstract Relative Location Aspects which are further subclassed by each possible host type:
- RelativePointLocationAspect - defines location for a PointLoad, subclasses:
- PointRelativeToPointAspect - defines location for a PointLoad on a point host - IDefinedPoint
- PointRelativeToCurveAspect - defines location for a PointLoad on a curve host - IDefinedCurve
- PointRelativeToSurfaceAspect - defines location for a PointLoad on a surface host - IDefineSurface
- RelativeCurveLocationAspect - defines location for a CurveLoad, subclasses:
- CurveRelativeToCurveAspect - defines location for a CurveLoad on a curve host - IDefinedCurve
- CurveRelativeToSurfaceAspect - defines location for a CurveLoad on a surface host - IDefinedSurface
- RelativeSurfaceLocationAspect - defines location for a SurfaceLoad, the only subclass is SurfaceRelativeToSurfaceAspect which defines relative location on a surface host - IDefinedSurface

SharedTopologyElements provide location and connectivity for Elements. There is one and only one subclass of SharedTopologyElement for each dimensionality:
SharedTopologyElements are Model-scope resources that never have a parent Element.
SharedTopologyElements are generally immutable, except for two use cases:
- Move Model (translate or rotate the entire structural model)
- Stretch Model (stretch a portion of a structural model)
Stretching is not always possible. Stretching the model is not allowed unless the entire model data can be updated to be valid.
Instead of being modified, ShareTopologyElements are typically replaced. For example: Edge that is split is replaced by two Edges.
Opposite to PrivateTopologyElements, all instances of SharedTopologyElement classes have graphics.

Sheet is a FaceSet that does not define the boundary of a Region (future).
Sheet's boundary is defined by its child Faces. Every Face in a Sheet must have the same Surface (the motivation for this is to provide a single surface-based coordinate system for SurfaceMembers).
Every Sheet has a parent (ISheetOwner) that is one of the following:
- SurfaceMember
- SurfaceMemberRegion (and hence SurfaceMemberModifier and SurfaceMemberOpening)
Sheets are never shared.

A support member in StructuralAnalysis represents a StructuralAnalysisElement that is an analytical support. Currently, StructuralAnalysis schema includes PointSupports, CurveSupports and SurfaceSupports. Support elements have no direct physical meaning, they are interpreted by some applications to represent some type of support. Support connects to (supports) to elements that share same connectivity (SharedTopologyElements). Each Support should refer to SupportBehavior which define how support behaves at specific connectivity.
Each Support defines a simplified version of a more complex structure. e.g. Substructure elements - piles, mat foundations would be considered in a Superstructure application as Supports. Both Substructure and Superstructure elements would be stored in same Structural Analysis model. SupportRepresentsMembers relationship allows defining which Members are represented by a Support.

SurfaceMember (Surface Member) Sealed EntityClass
Defines a Member that is located by a Sheet.
Base Class: StructuralAnalysis:Member
Represents Member that has one dimension (thickness) much smaller than its other dimensions and is surface-like in nature. Some examples are slabs, wall and spread footings.
SurfaceMember provides a basic set of capabilities that can be used to model most real-world situations:
- SurfaceMembers with planar outlines
- SurfaceMembers with polygon openings
- Non-planar SurfaceMembers with planar outlines (future)
- SurfaceMembers with varying thicknesses (future)
- SurfaceMembers with (mildly) warped surfaces (future)
SurfaceMember's analytical location is defined by a child Sheet. SurfaceMember always has a local coordinate system (RST):
- RAxis is defined by inherited RAxis property from IDefinedSurface mixin
- TAxis matches direction of SurfaceMember's Sheet's normal
- SAxis is defined by cross product of TAxis and RAxis
- Origin is defined by inherited Origin property from IDefinedSurface mixin
Not all properties of SurfaceMember are defined in SurfaceMember class. There are two additional types of properties that can be assigned to a SurfaceMember:
- Mandatory SurfaceMember properties, that can be repeated in multiple SurfaceMembers are grouped by a SurfaceType, these could include material, thickness, etc.
- Optional properties, that define unique behavior for that SurfaceMember that might not exist at all. These behaviors are assigned by MemberBehaviorAspect instances. A single SurfaceMember might have multiple different type behavior aspects assigned but only one of each kind
Complex SurfaceMembers are defined using three different classes:
- SurfaceMember - the SurfaceMember itself
- SurfaceMemberModifier - a region of the SurfaceMember that has different properties. Child of SurfaceMember that is being modified
- SurfaceMemberOpening - an opening in the SurfaceMember. Child of SurfaceMember that the opening modifies

Defines SurfaceMember region which has different behavior at that region than the rest of the SurfaceMember. It could have different thickness, material or other structural properties. SurfaceMemberRegions are permanently tied to the SurfaceMember they are created with. Regions can be removed from the model, but they cannot be switched from one SurfaceMember to another. If the SurfaceMember is removed from the model, the SurfaceMemberRegion is automatically removed from the model. SurfaceMemberRegions are child instances of SurfaceMember.
SurfaceMemberRegion has a single child Sheet to define its area. Each SurfaceMemberRegion's Sheet's Face must be referenced by a Sheet that is used to define location for parent SurfaceMember.

Provides connectivity information for all Structural Analysis elements.
There are two types of topology elements:
- SharedTopologyElements - Elements share these instances to define their geometry location and connectivity with other elements
- PrivateTopologyElements - These are owned by elements through PrivateTopologyElement's Parent property. These are usually used to group SharedTopologyElements for required used case, e.g: Group multiple Edges to a Loop to define boundary for a Slab.
All Topology Elements within a Model have the same Origin, Roll, Pitch and Yaw. This matches the approach of IFC's IfcStructuralAnalysisDomain and simplifies many calculations within Elements in the Model.

Vertex (Vertex) Sealed EntityClass
An identified location in 3D space.
Base Class: StructuralAnalysis:SharedTopologyElement
Vertices provide point location and connectivity at a point. StructuralAnalysisElements which refer to the same Vertex are connected and can transfer forces between each other. There can be multiple Vertices at the same spatial point, however elements that reference these vertices are not treated as connected. By default all elements which refer to the same Vertex are fixed at that spatial point. Default fixities for each of the 6 degrees of freedom can be adjusted with these instances:
Vertices are Model-scope shared resources that never have a parent Element.
Unlike other SharedTopologyElements, Vertices can be directly referenced by non-topology elements, e.g. PointLoad, PointSupport. However, these classes should not reference Vertex directly but use IDefinedPoint mixin instead, which is extended by Vertex class. Topology classes that reference Vertex are:
- Edge uses Vertices to define its start and end points. Edges referring to the same Vertex are connected
- Face can have internal vertices, bounded by its outer Loop. For example a slab that is supported by a column: here the column would indirectly refer to a Vertex which would also be shared with the Face that defines the Slab

Wire is a Path that does not define the boundary of a Face. Wires may be open or closed.
Every Wire has a parent that is one of the following:
CurveSupport - defines location and connectivity to Elements that are supported by current CurveSupport
Face - never used for defining Face location, only used to define connectivity to other members, e.g: Slab which has a beam under it, here Face would define the Slab which would have an internal Wire that shares Edges with another Wire that defines the beam
CurveMember - There will be always a single Location Wire that defines CurveMember location. However, CurveMember might have additional Sub Wires that define different fixities for some of the Edges. All Edges of Sub Wires must be referenced by the Location Wire. Location and Sub Wires are differentiated by using different relationships to define their parent:
- CurveMemberOwnsLocationWire for defining location wire
- CurveMemberOwnsSubWire for defining sub wires
Wires are never shared.

An Element that directly or indirectly defines a curve location and a clear coordinate system with the z-axis along the curve. The Element may have cardinal points defined; if not all the cardinal points should be considered to lie on the z-axis.
Applies To: Element
Commonly used for defining relative location for PointLoad and CurveLoad. IDefinedCurve is usually implemented by CurveMember and CurveSupport classes. Applications that work with Loads should reference host Members through IDefinedCurve mixin and PointRelativeToCurveAspect or CurveRelativeToCurveAspect.
Properties
| Name | Description | Label | Category | Read Only | Priority |
|---|---|---|---|---|---|
| Orientation | Orientation (normal) vector of the curve. | Orientation | false | 0 |
IDefinedPoint (Point Location definition) Abstract Mixin
An Element that directly or indirectly defines a point in 3D space.
Applies To: Element
Commonly used for defining relative location for PointLoad. IDefinedPoint is usually implemented by Vertex class. However, it is possible that in the future additional elements will implement this mixin. its is recommended for applications that work with PointLoads, to reference Vertices through IDefinedPoint mixins and PointRelativeToPointAspect.
IDefinedSurface (Surface Location definition) Abstract Mixin
An Element that directly or indirectly defines a surface location and a clear coordinate system with the x and y axes in the surface. The Element may have a top, bottom and center defined; if not, the top and bottom and center should be considered to lie on the surface.
Applies To: Element
Commonly used for defining relative location for PointLoad, CurveLoad and SurfaceLoad. IDefinedSurface implemented by SurfaceMember and SurfaceSupport classes. Applications that work with Loads should reference host Members through IDefinedSurface mixin and PointRelativeToSurfaceAspect, CurveRelativeToSurfaceAspect or SurfaceRelativeToSurfaceAspect.
Properties
| Name | Description | Label | Category | Read Only | Priority |
|---|---|---|---|---|---|
| SurfaceOrigin | Point on the surface defining the start of its local coordinate system. | Surface Origin | false | 0 | |
| RAxis | First vector defining the local coordinate system. This vector should be from tangent plane at the origin point of the surface. | RAxis | false | 0 |
ILoadCondition (Load Condition) Abstract Mixin
A load case or a combination of multiple factored load containers used for analysis.
Applies To: Element
ILoopOwner (Loop Owner) Abstract Mixin
Element which uses child Loop to represent it's location.
Base Class: BisCore:IParentElement
Applies To: Element
Defines parent for a Loop. Each class which can have a Loop as a child should subclass from this mix-in. TopologyElements are smallest part of StructuralAnalysis schema, these classes should not reference directly any more complex entity (e.g. SurfaceMember, PointSupport), ILoopOwner allows to avoid the need of such direct relationship.
IPathsOwner (Paths Owner) Abstract Mixin
Element which uses child Paths to represent it's location.
Base Class: BisCore:IParentElement
Applies To: Element
Defines parent for a Path. Each class which can have a Path as a child should subclass from this mix-in. TopologyElements are smallest part of StructuralAnalysis schema, these classes should not reference directly any more complex entity (e.g. SurfaceMember, PointSupport), IPathOwner allows to avoid the need of such direct relationship.
ISheetOwner (Sheet Owner) Abstract Mixin
Element which uses child Sheet to represent it's location.
Base Class: BisCore:IParentElement
Applies To: Element
Defines parent for a Sheet. Each class which can have a Sheet as a child should subclass from this mix-in. TopologyElements are smallest part of StructuralAnalysis schema, these classes should not reference directly any more complex entity (e.g. SurfaceMember, PointSupport), ISheetOwner allows to avoid the need of such direct relationship.
IStoryAssignable (IStory Assignable) Abstract Mixin

Applies To: StructuralAnalysisElement
Indicates that an element can be assigned to a Story.
Properties
| Name | Description | Label | Category | Read Only | Priority |
|---|---|---|---|---|---|

IStructuralSurface (Solid Surface) Abstract Mixin
Element which is defined by a surface and a thickness.
Applies To: StructuralAnalysisElement
SurfaceMember and SurfaceMemberModifier require many of the same properties and behave in similar manners. Because of this similarity, both interfaces implement the same mixing - IStructuralSurface. IStructuralSurface always has a normal, which is provided by some other related element (Sheet).
Properties
| Name | Description | Label | Category | Read Only | Priority |
|---|---|---|---|---|---|
| PlacementSurface | Sheet defines area location for IStructuralSurface, the height of IStructuralSurface is defined by thickness(provided by related SurfaceType) which extrudes location area by that thickness. PlacementSurface allows to define how location area should be interpreted for extrusion - ether as start, end or center. These are the most common used cases. More flexibility is achieved by using Offset property. | Placement Surface | false | 0 | |
| Offset | PlacementSurface provides only a few cases for how to interpret the location area (Sheet). Offset provides more flexibility for less common cases, where it provides additional offset along the normal of IStructuralSurface. Both PlacementSurface and Offset properties can be used at the same time. | Offset | false | 0 | |
| LayoutDirection | Used to define direction for how to place Steel Deck profiles | Layout Direction | false | 0 |
