In many cases, it is necessary to only apply loads to a single edge of a surface. For example, if you want to apply the loading by walls or wind in a simplified way.
The "Free Line Load" option is suitable for this.
Usage in RFEM
Under the Loads area, you can find the "Free Line Load" dialog box.
In the "Load Case" list, select the load case to which you want to assign the load.
In the "Assigned to Surfaces" section, you can control the effect of the line load. Several options are available for selection in the list (see the New Free Line Load image):
- "Empty": The load does not act on any surfaces.
- All: The load is applied to all surfaces that are cut perpendicular to the projection plane, starting from the load locations.
- "Number": The load acts only on the surfaces of the specified numbers.
In the "Load distribution" list, you can control whether the load is uniform or linear.
Uniform: The line load acts with a constant magnitude.
Linear: The load has a linearly variable magnitude.
Under "Parameters," you can determine the load values of the free line load.
The "Load location" function allows you to define the coordinates between which the free line load should act.
