Defining any Concentrated Load Sequence with only One Member Load

Technical Article on the Topic Structural Analysis Using Dlubal Software

Technical Article

Arbitrary distributions of concentrated loads often occur in the load definition of beam structures.

These load specifications can be edited much faster in the model editing if the relation of point loads to each other can be made in a definition.

The RFEM and RSTAB programs provide a solution for this task, offering a user-defined concentrated load arrangement. This load function allows the definition of a freely defined point load sequence with any distances and force values in one data set.

Select

  • the "Force" Load Type and
  • the "User-Defined" Load Distribution

in the "Edit Load on Set of Members" dialog box. Then, you can accurately determine the load magnitude and distances of the concentrated loads by table input.

This option is very useful to simulate the loading of rafter beams on a purlin. Thus, due to the member load, a division of the purlin at the load application points is not necessary.
