Using Modified Stiffnesses for Dynamic Calculations
Tips & Tricks
To consider the distinctive material behavior of concrete elements in the determination of eigenfrequencies, you can first modify the stiffnesses in RFEM 5 or RSTAB 8, and then select the respective check box in the RF‑/DYNAM module.
In RFEM, you can activate or deactivate the consideration of the modified stiffnesses for the determination of deformations and internal forces in the global calculation parameters.
