Add-on modules DYNAM Pro - Equivalent Loads RF-DYNAM Pro - Equivalent Loads

In the input window 1.10 Equivalent Loads for RF-DYNAM Addition II (RFEM 5), there is the option to consider accidental torsional effects. Which calculation method is behind the calculation and which values need to be specified for Lx and Ly?


The Lx and Ly to be defined in the module reflect the Li floor dimension perpendicular to the seismic action. From each individual horizontal force (per FE nodal mass), a torsional moment Mi over -0.05 Li is determined.

Then, the double amount of exported load cases is shown, once with the torsional moment Mi rotating in positive and once in negative direction.
