The response spectrum analysis is one of the most frequently used design methods in the case of earthquakes. This method has many advantages, the most important one is the simplification.
The number of degrees of freedom in a node is no longer a global calculation parameter in RFEM (6 degrees of freedom for each mesh node in 3D models, 7 degrees of freedom for the warping torsion analysis). Thus, each node is generally considered with a different number of degrees of freedom, which leads to a variable number of equations in the calculation.
This modification speeds up the calculation, especially for models where a significant reduction of the system could be achieved (e.g. trusses and membrane structures).
- How can I enter or read out a response spectrum via the COM interface in DYNAM Pro?
- 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, I get the error no. 1759: "The Microsoft Excel Worksheet 'Acceleration Data' was not found." What could be the reason?
- 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?
- 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?
- There are two solving methods for a linear time history analysis available in the RF‑/DYNAM Pro add-on module. What is the difference between them?
- 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?
