Extension of RF-DYNAM Pro - Natural Vibrations for Time History Analysis and Multi-Modal Response Spectrum Analysis

The RF-/DYNAM Pro - Forced Vibrations add‑on module provides a tool for dynamic analysis of mechanical structures to external excitations. Various excitation functions can be defined in a tabular form, as harmonic loads or as a function of time. The time history analysis is performed either with the modal analysis or with the linear implicit Newmark analysis.

Using the multi‑modal and multi‑point response spectrum analyses, it is possible to perform seismic analyses. The required spectra can be created in compliance with the standards or user‑defined. The add‑on module contains an extensive library of accelerograms from earthquake zones, which can be used to generate response spectra.

  1. Features of Time History Analysis

    • Combination of user-defined time diagrams with load cases or combinations (nodal, member and surface loads as well as free and generated loads can be combined with functions varying over time)
    • Combination of several independent excitation functions
    • Extensive library of seismic events (accelerograms)
    • Linear implicit Newmark analysis or modal analysis in time history
    • Structural damping using Raleigh damping coefficients or Lehr's damping
    • Direct import of initial deformations from a load case or combination
    • Graphical display of results in a time history diagram
    • Export of results in user-defined time steps or as an envelope
  2. Features of Multi-Modal Response Spectrum Analysis

    • Response spectra of numerous standards (EN 1998, DIN 4149, IBC 2012, etc.)
    • User-defined response spectra or generated from accelerograms
    • Direction-relative response spectra approach
    • Manual or automatic selection of the relevant mode shapes of response spectra (5 % rule of EC 8 applicable)
    • Result combinations by modal superimposition (SRSS or CQC rule) and by direction superimposition (SRSS or 100 % / 30 % rule)
  3. Input Data

    Input

    It is necessary to enter the required response spectra, accelerations, or time diagrams. Dynamic load cases define the location and direction of response spectra effects as well as acceleration time, or force-time excitations.

    Time diagrams can be combined with static load cases which provide great flexibility. For the time history analysis, you can import the initial deformation from any load case or load combination.

  4. Calculation parameters for natural vibration cases

    Calculation

    The time history analysis is performed with the modal analysis or the linear implicit Newmark analysis. The time history analysis in this add‑on module is restricted to linear systems. Although the modal analysis represents a fast algorithm, it is necessary to use a certain number of eigenvalues to ensure the required accuracy of results.

    The implicit Newmark analysis is a very precise method, independent of the number of eigenvalues used, but requires sufficient small time steps for calculation. For the response spectra analysis, equivalent static loads are calculated internally. A linear static analysis is performed subsequently.

  5. Time course monitor for a periodic vibration

    Results

    Due to the integration of RF‑/DYNAM Pro in RFEM / RSTAB, you can incorporate numeric and graphic results from RF‑/DYNAM Pro – Forced Vibrations to the global printout report. Also, all RFEM options are available for a graphical visualization.

    The results of the time history analysis are displayed in a time course monitor. All results are plotted versus time. You can export the numeric values to MS Excel.

    In the case of a time history analysis, you can export results of the individual time steps or filter most unfavourable results of all time steps.

    The response spectra analysis calculation generates result combinations. Mode and load force combinations due to the components of earthquake action are used internally.
