Question
RF-/DYNAM Pro - Equivalent Loads includes the result tables "5.8/5.9/5.10 - Equivalent Loads." Which sum is displayed in the case of the "All mode shapes" option?Answer
The sum indicated in this table does not reflect the correct superposition according to the standard. This is a simple summing up of the equivalent loads. A superposition with the selected superposition rule (SRSS or CQC) is not performed in this table!Furthermore, there are differences if activating the accidental torsion in the add-on module. This leads to the generation of two load cases for each mode shape. They always contain the torsional moment in the positive and in the negative direction. As a result, the equivalent loads are doubled in this table.
