The author continues the discussion about the enveloping of response spectra at the base mat. The ultimate goal is to perform the most time-consuming analysis of the detailed model only once for a number of different soil foundations. In this paper the real-life example of 3D analysis is presented: conservatism of proposed approach is verified against conventional analyses.
