Add-on Module for RSTAB 8
DYNAM Pro – Equivalent Loads

In DYNAM Pro – Equivalent Loads, you can perform seismic analyses with multi‑point response spectrum analysis. You can create the response spectra required for this in compliance with the standards, or user-defined. From this, the equivalent static forces are generated.

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

RF-/DYNAM Pro - Equivalent Loads | Input

The input parameters relevant for the selected standards are suggested by the program in accordance with the rules. 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.

RF-/DYNAM Pro - Equivalent Loads | Calculation

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.

RF-/DYNAM Pro - Equivalent Loads | Results

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 contributions 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.

Pushover analysis in RFEM

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.
