Dynamic Behavior Of Torsionally Coupled Buildings For Foundations Embedded In An Elastic Stratum

The purpose of this work is to investigate the results of deformability of the soil medium which radiates energy, on the coupled lateral-torsional dynamic response of single story buildings under seismic loading. An efficient method idealized the whole structure-foundation-soil system with a three dimensional lumped parameter model with frequency-dependent foundation impedance functions for the two cases of a site, surface and embedded footing-layer on rigid substratum is presented.
