If you want your buildings on Australian soil to remain safe and stable even under turbulent conditions, these modules will help you.
Use the RF-/DYNAM Pro - Natural Vibrations add-on module for RFEM 5 / RSTAB 8 to determine natural frequencies and mode shapes.
The RF-/DYNAM Pro - Equivalent Loads module extension generates equivalent seismic loads using the multimodal response spectrum analysis. Among others, the Australian standard AS 1170.4 is implemented.
