Modal Analysis Add-on

Compared to the RF‑/DYNAM Pro - Natural Vibrations add-on module (RFEM 5 / RSTAB 8), the following new features have been added to the Modal Analysis add-on for RFEM 6 / RSTAB 9:

  • Preset combination coefficients for various standards (EC 8, ASCE, and so on)
  • Optional neglect of masses (for example, mass of foundations)
  • Methods for determining the number of mode shapes (user-defined, automatic - to reach effective modal mass factors, automatic - to reach the maximum natural frequency)
  • Output of modal masses, effective modal masses, modal mass factors, and participation factors
  • Masses in mesh points displayed in tables and graphics
  • Various scaling options for mode shapes in the Result navigator
