r4.05.08 Method for taking into account the Floor-Material interaction

Summary:

In seismic studies, it is often necessary to produce floor spectra for buildings where equipment is modelled by masses added to the floor. These additional masses impact floor spectra. The method proposed here makes it possible to modify the floor spectra by taking into account the interaction of the masses and the floor.
