Response Spectrum Analysis Add-on

Technical Article on the Topic Structural Analysis Using Dlubal Software

  • Knowledge Base

Product Feature

Compared to the RF-/DYNAM Pro - Equivalent Loads add-on module (RFEM 5 / RSTAB 8), the following new features have been added to the Response Spectrum Analysis add-on for RFEM 6 / RSTAB 9:

  • Response spectra of numerous standards (EN 1998, DIN 4149, IBC 2018, etc.)
  • User-defined response spectra or those generated from accelerograms
  • Approach of direction-related response spectra
  • Results are stored centrally in a load case with underlying levels to ensure clarity
  • Accidental torsional actions can be taken into account automatically
  • Automatic combinations of seismic loads with the other load cases for use in an accidental design situation

RF -DYNAM Pro - Forced Vibrations

Dynamic Analysis

In the Response Spectrum Analysis add-on, seismic analysis is performed using multi-modal response spectrum analysis. The spectra required for this can be created in compliance with the standards or can be user-defined. The equivalent static forces are generated from this. The add-on includes an extensive library of accelerograms from seismic zones. These can be used to generate response spectra.
