FAQ 004421 | Can RF-STEEL AISC optimize cross-sections for Serviceability?

Question:
Can RF-STEEL AISC optimize cross-sections for serviceability?

Answer:
The RF-STEEL AISC module does not optimize cross-sections for the Serviceability Limit State design. Optimization is only calculated for the Ultimate Limit State design. 

Users must manually adjust the cross-section in RFEM or within the add-on module and can export the cross-section back into RFEM. In either scenario, the model must be rerun in order to calculate the correct internal forces with adjusted member size.
