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.

Specification in the excel

Name of the column header
Type of data
Value example or enum definition
Required value
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)
Id
String
39f238a5-01d0-45cf-a2eb-958170fd4f39
no
Unique attribute designation

Notes

An example of use of Repeat (n) is given below. The forces are distributed uniformly meaning that the value Delta x is used for uniform distribution along the 1D member for multiple point forces.
