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.

Specification in the excel

Column header	Data type	Example / enum definition	Required	Description
Name	String	LF5	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
Distribution	Enum	Uniform Trapez	yes	The load may be either constant along its length or linearly variable (trapezoidal).
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
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	yes, if Direction = X,Y or Z and Distribution = Trapez	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	LC1	yes	The name of the load case to which the force belongs
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.
Coordinate Y [m]	String	0.500; 1.050; 2.650; -1.500	yes	The list of Y coordinates of the nodes which define the geometry of the line free load. Each coordinate is separated by semicolon and space.
Coordinate Z [m]	String	0.000; 0.000; 0.000; 0.000	yes	The list of Z coordinates of the nodes which define the geometry of the line free load. Each coordinate is separated by semicolon and space.
Segments	String	Line; Circular Arc; Bezier; Parabolic arc; Spline	yes	List of the shape of each segment which is part of the curve, separated by semicolon if there are multiple
Coordinate system	Enum	Global Local	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.
Id	String	39f238a5-01d0-45cf-a2eb-958170fd4f39	no	Unique attribute designation
