How can I consider the second-order analysis for seismic design?

Answer

In RF‑DYNAM Pro ‑ Natural Vibrations, it is possible to import the geometrical stiffness matrix. You can use it to consider the second‑order analysis. The equivalent lateral loads for earthquakes generated with the RF-DYNAM Pro - Equivalent Loads add-on module take this stiffness modification into account.

In the attached file, it is described when the second-order analysis according to ASCE 7-16 has to be considered and which options are offered by the RF-DYNAM Pro modules.
