• User-defined response spectra
• Direction-relative response spectrum approach
• Relevant mode shapes for the response spectrum can be selected manually or automatically (5% rule from EC 8 can be applied)
• Generated equivalent static loads are exported to load cases, separately for each modal contribution and separately for each direction
• Result combinations by modal superposition (SRSS and CQC rule) and direction superposition (SRSS or 100% / 30% rule)
• Signed results based on the dominant eigenmode can be displayed

The input parameters of the selected standards are proposed by the program. Furthermore, it is possible to enter response spectra manually. Dynamic load cases define a direction of response spectra effects and the structure eigenvalues that are relevant for the analysis.

Equivalent static loads are generated separately for each relevant eigenvalue and excitation direction. They are exported to static load cases to perform the linear static analysis in RFEM/RSTAB.

The equivalent load analysis calculation generates load cases and result combinations. The load cases include the generated equivalent loads, which are subsequently superimposed in result combinations. First, the modal responses are superimposed with the SRSS or CQC rule. Signed results based on the dominant mode shape are possible.

Afterwards, the directional components of earthquake actions are combined with the SRSS or the 100% / 30% rule.

In RFEM, it is possible to determine pushover curves (also called capacity curves) and export them to Excel.

With the RF-DYNAM Pro - Equivalent Loads add-on module, it is possible to generate load distribution automatically in accordance with a mode shape and export it as a load case to RFEM.
