Seismic analysis of mono-symmetric multi-storey buildings including foundation interaction

A method of analysis for the earthquake response of multi-storey mono-symmetric buidlings founded on flexible foundations is presented. The analysis also includes the sway (P-Δ) effects. The structural model considered herein is a linear N-storey building on a rigid footing resting on the surface of a linear elastic half-space. The system has 2N + 3 degrees of freedom. The governing equations are developed considering the motions of each floor …
