StructuralPointAction¶
Point force
Instances of StructuralPointAction define a point load applied to the node (StructuralPointConnection) and also the location of the point load on a 1D member (StructuralCurveMember).
The point force can be defined in three main directions (global or local coordinate system). Every point force has to be assigned to a load case.

Example / enum definition |
Required |
Description |
---|---|---|---|---|
Name |
String |
F3 |
yes |
Human readable unique name of the force |
Type |
String |
Standard |
no |
This property defines what the load is caused by, E.g. Standard, Wind, Snow, Self weight, Hoar Frost, Predefined, Plane Load, Water Pond, Water Pressure, Soil Pressure, Generated Water, Generated Soil |
Direction |
Enum |
X Y Z Vector |
yes |
Specifies the base direction of the load X, Y, Z - action will be applied in one of these directions Vector - size and direction calculated from vector |
Force action |
Enum |
On beam In node |
yes |
Specifies on which type of object the force acts |
Reference node |
String |
N3 |
yes, if Force action = In node |
The name of the reference node |
Reference member |
String |
B1 |
yes, if Force action = On beam |
The name of the reference member |
Value [kN] |
Double |
-150 |
yes, if Direction = X,Y or Z |
Specifies the size of the load in, acts in one direction |
Vector (X;Y;Z) [kN] |
String |
(10;10;0) |
yes, if Direction = Vector |
Specifies the size of the load in , direction by vector |
Load case |
String |
LC2 |
yes |
The name of the load case to which the force belongs |
Coordinate system |
Enum |
Global Local |
yes |
Defines the co-ordinate system of the member in which the load is applied For ” Local”, coordinate system is defined by node or 1D member |
Origin |
Enum |
From start From end |
yes, if Force action = On beam |
Specifies where the origin for the position co-ordinate measurement is |
Coordinate definition |
Enum |
Absolute Relative |
yes, if Force action = On beam |
Specifies the definition of the position. It may be absolute or relative |
Position x [m] |
Double |
value in meters for Coordinate definition = Absolute 5,25 value in percentage for Coordinate definition = Relative 1,0 |
yes, if Force action = On beam |
Defines the position of the load on the 1D member in local coordinate system in relative or in absolute coordinates [m] |
Repeat (n) |
Integer |
0 |
yes, if Force action = On beam |
Defines the number of forces acting on the beam. If the number is greater than 1, the forces are distributed uniformly over the 1D member |
Delta x [m] |
Double |
0,3 |
yes, if Repeat (n) > 1 |
Defines the distance between forces acting on the 1D member in relative or in absolute coordinates [m] (only applicable when ForceAction = OnBeam) |
