The stiffness of gas given by the ideal gas law pV = nRT can be considered in the nonlinear dynamic analysis.
The calculation of gas is available for accelerograms and time diagrams for both the explicit analysis and the nonlinear implicit Newmark analysis. To determine the gas behaviour correctly, at least two FE layers for gas solids should be defined.
Frequently Asked Questions (FAQs)
- Which time step should I select for the calculation of the time history analysis in the RF‑/DYNAM Pro add‑on module?
- After running a time history analysis, I am not able to see all results on surfaces. Is there a possibility to show them?
- Is it possible to perform a dynamic analysis of the initial deflection of a structural component in RFEM or RSTAB?
- Is it possible to consider the static zero position in a time history analysis?
- Which programs and add-on modules are suitable for the structural analysis and design of steel structures?
- Is it possible to display or export certain results over a period of time from the time history calculation in RF‑DYNAM Pro - Forced Vibrations?
- In RF‑/DYNAM Pro, the "From self-weight of structure" option is available in a mass case. Is it always necessary to activate this option in order to consider the dead load of the structure?
- How can I consider prestressed cables in RF‑/DYNAM Pro?
- In RF-/DYNAM Pro, the Rayleigh damping is available. How do I determine and use these factors?
- How can I display the results of the RF‑/DYNAM Pro add-on module in the printout report?
