Dynamic analyses in RFEM 6 and RSTAB 9 can be performed in several add-ons. The Modal Analysis add-on performs natural vibration analyses. They are the basis for all other dynamic add-ons. The "Response Spectrum Analysis" add-on provides you with the option to perform a seismic analysis using the multi-modal response spectrum analysis. The "Time History Analysis" add-on allows for a dynamic structural analysis of external excitations that can be defined as a function of time. The "Pushover Analysis" add-on allows you to determine the maximum nonlinear response of a structure to seismic loads. The "Harmonic Response Analysis" add-on is still under development.
This manual describes the dynamic analysis add-ons for RFEM 6 and RSTAB 9.
