# 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:

Type of data
Value example or enum definition
Required value
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
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
