Extension of RF-/DYNAM Pro - Natural Vibrations Module for Static Load Analysis Using Multi-Modal Response Spectrum Analysis

The RF-/DYNAM Pro - Equivalent Loads add‑on module performs seismic analysis using the multi-modal response spectrum analysis. The required spectra can be created according to the standards or user‑defined. Subsequently, the equivalent static loads are generated.

      •  SIST EN 1998-1:2005/A101:2006 (Slovenia)
    • Input of user-defined response spectra
    • Direction-relative response spectra approach
    • Manual or automatic selection of the relevant mode shapes for response spectra (5 % rule from EC 8 applicable)
    • Generated equivalent static loads exported into load cases separately for each mode and direction
    • Result combinations by modal superimposition (SRSS rule) and by direction superimposition (SRSS or 100 % / 30 % rule)
  2. Input

    The input parameters of the selected standards are proposed by RF-/DYNAM Equivalent Loads. Furthermore, it is possible to enter response spectra manually. Dynamic load cases define a direction of response spectra effects and the structure eigenvalues that are relevant for the analysis.

  3. Calculation parameters


    Equivalent static loads are generated separately for each relevant eigenvalue and excitation direction. They are exported to static load cases to perform the linear static analysis in RFEM/RSTAB.

  4. Equivalent loads from mode shapes


    The equivalent load analysis calculation generates load cases and result combinations. The load cases include the generated equivalent loads, which are subsequently superimposed in result combinations. Before, the module superimpose the modes (SRSS rule).

    Afterwards, the load forces are superimposed due to the components of earthquake actions (SRSS or 100 % / 30 % rule).
