StructuralSurfaceActionDistribution object describes how surface load can be distributed to other members.
Name of the column header | Type of data | Value example or enum definition | Required value | Description |
Name | String | FL1 | yes | Human readable unique name of the Arbitrary definition |
Type | Enum | Nodes Edges Beams and edges | yes | Defines where the load should be distributed. Nodes - load is expected to be distributed to nodes of StructuralSurfaceActionDistribution <b></b> Edges - load is expected to be distributed to edges of StructuralSurfaceActionDistribution <b></b> Beams and edges - load is expected to be distributed to edges and specified beams of StructuralSurfaceActionDistribution |
Nodes | String | N81; N263; N659; N660 | yes | All nodes that belongs to StructuralSurfaceActionDistribution member and defines its geometric shape. The names of the nodes are separated by ; (semicolon) and space. |
Edges | String | Line; Line; Circular Arc; Line or Line;Spline-5;Line;Parabolic Arc;Line | yes | Defines the shape of the curve between two next nodes (or more nodes depends on edge type). Supported strings are:
Where "x" number of nodes defining the spline The names are separated by ; (semicolon) and space. It possible to also define circle geometry by using "Circle and Point" or "Circle by 3 points". In case of "Circle and point" two nodes have to be defined, centre of the circle and a point on a circle. The circle defined by two points is always horizontal. |
Layer | String | Load panel | no | Custom created layer. The layer can thus comprise entities that have something in common (e.g. one floor, columns of one floor, columns of the same length, etc.) |
LCS Type | Enum | x by vector y by vector Tilt of vector defined by point | yes | Defines type of the local coordinate system of the StructuralSurfaceActionDistribution. Option “Tilt of vector defined by point” allows change of orientation of the LCS to one point. For this, you have to specify coordinates of the vector. For further understanding see Introduction |
Coordinate X [m] | Double | 1 | yes | Coordinate of the vector of the LCS in X direction |
Coordinate Y [m] | Double | 0 | yes | Coordinate of the vector of the LCS in Y direction |
Coordinate Z [m] | Double | 1,2 | yes | Coordinate of the vector of the LCS in Z direction |
LCS Rotation [deg] | Double | 45.00 | yes | This value defines the rotation of local axes of the StructuralSurfaceActionDistribution member. It is angle around Z axis (axis which is perpendicular to plane) and defines distribution angle. Positive value = anti clock wise. |
Distribution to | Enum | One way - X One way - Y Two way | yes | Defines how the load will be distributed. <b></b> One way - X - Load will be distributed only to members parallel with X direction (X axis of LCS) <b></b> One way - Y - Load will be distributed only to members parallel with Y direction (Y axis of LCS) <b></b> Two way - Load will be distributed equally to both directions |
Load applied to | String | B1 ; B2 ; B3 ; B5 | yes | Allows to define the subset of loaded beams. Taken into account only if Type = Beams and edges If blank = all beams are loaded |
Id | String | 39f238a5-01d0-45cf-a2eb-958170fd4f39 | no | Unique attribute designation |
