RFEM 5 Add-on Modules – Dynamic Analysis

The RF-DYNAM Pro – Natural Vibrations add‑on module allows you to quickly and easily analyze natural frequencies and mode shapes of member, surface, and solid models.

All necessary input values can be imported directly from RFEM 5. Powerful eigenvalue solvers (such as Lanczos, subspace iteration, and so on) are available to determine up to 9,999 eigenvalues.

RF-DYNAM Pro – Forced Vibrations allows for a dynamic analysis of supporting structures with regard to external excitation, including various excitation functions and time history analysis by using a modal analysis or Newmark solver.

The module performs seismic analysis using the multi-modal and multi-point response spectrum analysis. It provides standard-compliant or user-defined spectra and a library of accelerograms for generating the response spectra.

The RF-DYNAM Pro – Equivalent Loads add-on module is an extension of the RF-DYNAM Pro – Natural Vibrations add-on module for the static load analysis using the multi-modal response spectrum analysis. It allows for seismic analyses using standard-compliant or user-defined response spectra to generate equivalent static forces.

The add-on module supports a wide range of international standards and provides comprehensive features for the analysis and documentation of seismic actions on structures.

The RF-DYNAM Pro – Nonlinear Time History add‑on module enables nonlinear dynamic structural analysis for an external excitation. You can define various excitation functions in tables, as harmonic loads, or as a function of time. The nonlinear time history analysis is performed using the nonlinear implicit Newmark analysis and an explicit solver. This module extension removes the restriction to linear systems in dynamics.
