Defining any Concentrated Load Sequence with only One Member Load
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.
- 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.

In this article, the adequacy of a 2x4 dimension lumber subject to combined bi-axial bending and axial compression is verified using RF-/TIMBER AWC add-on module. The beam-column properties and loading are based on example E1.8 of AWC Structural Wood Design Examples 2015/2018.

- The information about the limit time for the fire resistance design R in the RF‑TIMBER Pro add-on module is missing in the printout report. Is it posssible to add this information to the printout report?
- I would like to convert the load from a surface load to a line load, that is, to apply it to the individual beams. How can I do this without using an auxiliary area?
