New Generation of Dynamic Structural Analysis

RF-/DYNAM Pro Add-on Modules for Dynamic Analysis

24. February 2015

With the new RF-/DYNAM Pro add-on modules, dynamic structural analysis becomes more conveniently. The modules are clearly arranged with tabs and they have several powerful new features compared to the previous versions. Here is a small selection.

RF-/DYNAM Pro – Natural Vibrations

With this add-on module, you can determine natural frequencies and mode shapes.

Compared to the previous module RF-/DYNAM Basic, the following new features have been implemented among other things:

  • Mass cases, mass combinations and natural vibration cases can be defined
  • Automatic determination of the combination factors
  • Direct import of masses from static load cases or load combinations
  • Failing members, deactivated members, prestresses, modified stiffnesses from RFEM and RF‑CONCRETE are taken into account
  • Improvement of the calculation by a consistent mass matrix in RFEM

RF-/DYNAM Pro – Forced Vibrations

In this add-on module, you can analyze forced vibrations and you can use the multi-modal response spectrum analysis and time history analysis.

Among other things, these new features have been implemented in comparison to the previous version RF-/DYNAM Addition I:

  • Response spectra from various standards can be imported and created (EC 8, IBC 2012, SIA 261, GB 50011, O.G. 23089 etc.)
  • Relevant mode shapes for the response spectrum can be selected manually or automatically (the 5% rule from EC 8 can be applied)
  • Import of different support node excitations in X, Y and Z directions
  • Result combinations by modal superposition (SRSS or CQC rule) and by direction super‑positioning (SRSS or 100% / 30% rule)
  • Time course diagram (comparison of result points directly in the diagram; export of graphical representation to Excel table possible)
  • Combination of functions of time with static load cases (member, surface and free loads)
  • Import of initial deformations from load cases

RF-/DYNAM Pro – Equivalent Loads

In this add-on module, you can generate equivalent seismic loads according to the multi-modal response spectrum analysis.

Compared to RF-/DYNAM Addition II, the following features have been implemented among other things:

  • Implementation of additional standards
  • Relevant mode shapes for the response spectrum can be selected manually or automatically (the 5% rule from EC 8 can be applied)
  • Import of different support node excitations in X, Y and Z direction
  • Output of equivalent loads separately for each selected mode shape and excitation direction
  • Result combinations by modal super‑positioning (SRSS rule) and by direction super-positioning (SRSS or 100% / 30% rule)
