Determining Equivalent Loads According to DIN EN 1998

Tips & Tricks

RF-/DYNAM Addition II allows you to determine loads due to equivalent seismic loads according to the multi‑modal response spectrum method. In the example shown here, this was done for a multi‑mass oscillator. The cantilever was therefore subdivided into seven nodes. In the calculation, the equivalent load and the distribution on the individual nodes were determined with the first eigenvector of the system. The required eigenfrequency and the according equivalent mass factor were determined in RF‑/DYNAM Basic.
