GEO5 FEM Earthquaqe (Add-on)

The FEM Earthquaqe add-on requires FEM (Proper) as the underlying program. The FEM Earthquake is used for the dynamic analysis of geotechnical structures exposed to ground motion. It either accepts user-defined accelerograms or generates ground motion histories compatible with the specified response spectrum. The program outputs the progress of displacements, stresses, internal forces, and other mechanical quantities and summarizes their maximum values. It also performs modal analysis to acquire eigenfrequencies and eigenmodes of the system for setting the material damping.
