StructuralSurfaceActionDistribution

Load panels, Load distribution

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

Warning

The name of the excel sheet is StructuralSurfaceActionDistri due to sheet name length limitation.

Specification in the excel

Column header	Data type	Example / enum definition	Required	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-# Where “#” 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	String	39f238a5-01d0-45cf-a2eb-958170fd4f39	no	Unique attribute designation
