StructuralCurveActionFree¶
Free line force
The Free line load is related to slabs. The load is not defined by the entity it acts on, but by a specific load border. Free loads are defined by means of “loading entities” that may overlap or affect one or more slabs.

Enum |
Uniform Trapez |
yes |
The load may be either constant along its length or linearly variable (trapezoidal). |

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 |
Value 1 [kN/m] |
Double |
-150 |
yes, if Direction = X,Y or Z |
Specifies the first size of the load in kiloNewtons per meter |
Value 2 [kN/m] |
Double |
-180 |

Specifies the second size of the load in kiloNewtons per meter |
Vector 1(X;Y;Z) [kN/m] |
String |
(10;10;0) |
yes, if Direction = Vector |
Specifies the first size of the load in, direction by vector Note: Vector1 and Vector2 needs to be in same direction |
Vector 2(X;Y;Z) [kN/m] |
String |
(20;20;0) |
yes, if Direction = Vector and Distribution = Trapez |
Specifies the second size of the load in, direction by vector Note: Vector1 and Vector2 needs to be in same direction |
Load case |
String |

Coordinate X [m] |
String |
0.000; 2.050; 4.850; -2.000 |
yes |
The list of X coordinates of the nodes which define the geometry of the line free load. Each coordinate is separated by semicolon and space. |

yes |
Defines co-ordinate system of the member in which the load is applied |
Location |
Enum |
Length Projection |
yes |
Specifies whether the load is “put directly on an inclined 1D member” or whether the “projection on plan” is defined. |
