With RF-/DYNAM Pro Equivalent Loads, it is possible to perform an equivalent load calculation using the multimodal response spectrum method. In the example shown here, this was done for a multi‑mass oscillator.
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.
- Which programs can I use to calculate and design power plants?
- I noticed deviations from the map of DIN EN 1998‑1 or DIN 4149 in the online service "<a href="https://www.dlubal.com/en/solutions/online-services/snow-load-wind-speed-and-seismic-load-maps" target="_blank">Geo-Zone Tool: Snow, Wind, and Seismic Zone Maps</a>." Can you tell me which map is current and thus governing?
- How can I enter or read out a response spectrum via the COM interface in DYNAM Pro?
- Is it possible to also create a user-defined response spectrum in RF‑/DYNAM Pro?
- RF-/DYNAM Pro - Equivalent Loads includes the result tables "5.8/5.9/5.10 - Equivalent Loads." Which sum is displayed in the case of the "All mode shapes" option?
- What is the approach for seismic design in RFEM/RSTAB?
- I have used the RF‑/DYNAM Pro add-on module to generate the governing result combinations of seismic loads. What is the next procedure to perform the design of the individual structural components?
- What method is applied in the RF‑/DYNAM Pro - Equivalent Loads add-on module?
- Is there any option to generate a "response spectrum according to the standard" with user-defined parameters in the RF‑DYNAM Pro add-on module?
- What should be considered when using a failure of columns under tension in the RF‑/DYNAM Pro – Equivalent Loads add-on module?
