With the RF-/TIMBER Pro add-on module, it is possible to perform the vibration analysis known from DIN 1052 for the design according to EN 1995-1-1. In this analysis, the deflection under permanent and quasi-permanent action at the ideal one‑span beam may not exceed a limit value (6 mm according to DIN 1052). If you consider the relationship between natural frequency and deflection for a hinged single -span beam loaded with a constant distributed load, the 6 mm result in a minimum natural frequency of about 7.2 Hz.
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.
- 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?
- 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?
- How can I display the results of the RF‑/DYNAM Pro add-on module in the printout report?
- What should be considered when using a failure of columns under tension in the RF‑/DYNAM Pro – Equivalent Loads add-on module?
- After the calculation in the RF‑/DYNAM Pro - Equivalent Loads add-on module, the size of my file has increased significantly. The performance has worsened enormously. What could be the reason for this?
- I would like to calculate and design "temporary structures." What do I need for this?
- Which programs can I use to calculate and design power plants?
