StructuralSurfaceActionDistri

Load panels, Load distribution

StructuralSurfaceActionDistribution object describes how surface load can be distributed to other members.

Specification in the excel

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
Edges - load is expected to be distributed to edges of StructuralSurfaceActionDistribution
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:
  • Line
  • Circular Arc
  • Circle by 3 points
  • Circle and Point
  • Parabolic arc
  • Bezier
  • Spline-x
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.
One way - X - Load will be distributed only to members parallel with X direction (X axis of LCS)
One way - Y - Load will be distributed only to members parallel with Y direction (Y axis of LCS)
Two way - Load will be distributed equally to both directions
Load applied to
String
B1 ; B2 ; B3 ; B5
no
Allows to define the subset of loaded beams.
Taken into account only if Type = Beams and edges
If blank = all beams are loaded
Id
