Line force on slab edge

Parameters

Name	Is used for the identification of the load.
Direction	Specifies the base direction of the load.
Type	The load may be a force load, wind load, snow load, self-weight or predefined load.
Distribution	The load may be either constant along the edge or linearly variable (trapezoidal).
Value	Specifies the size of the load.
System	Defines the co-ordinate system in which the load is applied.
Location	Specifies whether the load is "put directly on an inclined member" or whether the "projection on plan" is defined. (Applicable only for loads defined in GCS system).
Edge	Specifies the edge where the load is acting.
Position x1	Defines the position of the load beginning on the edge.
Position x2	Defines the position of the load end on the edge.
Co-ordinate definition	Specifies the definition of the position. It may be absolute or relative.
Origin	Tells where the origin for the position co-ordinate is.

Value

The meaning of the Value depends on the Type of load.

• For Force load, the Value is the real value of the load.

• For Wind load, the Value represents the loading width. The real wind pressure is defined by wind curve specified in the project settings.

• For Snow load, the meaning is analogous to Wind load.

• For Predefined load the meaning is analogous to Wind load.

System

The definition of load direction may be defined:

• in the local co-ordinate system of a edge,

• in a selected user-co-ordinate system,

• in the global co-ordinate system.

Location

The location depends on the setting of the System.

For local and user co-ordinate system, the location can be only Length.

However, for load defined in the global co-ordinate system, also a Projection may be selected.

For more information see chapter Direction of loads.

Co-ordinate definition

The location of the load on the edge may be defined in absolute or relative co-ordinates. If absolute co-ordinates are selected, the distance is defined in real length units set for the project. In the case of relative co-ordinates, the position of the load on the edge is defined by value from within the interval <0, 1>. In both cases, the distance is measured from the point defined in the Origin item.
