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.

    • 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 CQC rule)
    • Signed results based on the dominant mode shape can be generated
  2. Input Data

    Input

    The input parameters of the selected standards are proposed by the program. 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

    Calculation

    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

    Results

    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. First, the modal responses are superimposed with the SRSS or CQC rule.

    Afterwards, the directional components of earthquake actions are combined with the SRSS or the 100 % / 30 % rule.

  5. Display of pushover curve in the calculation diagrams in RF-DYNAM Pro

    Pushover Analysis

    In RFEM, it is possible to determine pushover curves (also called capacity curves) and export them to Excel.

    With the RF-DYNAM Pro - Equivalent Loads add-on module, it is possible to generate load distribution in accordance with a mode shape and export it as load case to RFEM.
