Compared to the RF-/DYNAM Pro - Natural Vibrations add-on module (RFEM 5 and RSTAB 8), the following new features have been added to the Modal Analysis add-on for RFEM 6 and 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
- Tabular and graphical output of masses in mesh points
- Various scaling options for mode shapes in the result navigator
