摘要

The purpose of this work is to study the response of 3D models of conventional multi-storey R/C buildings, in either bending or shearing mode behavior, in the presence or absence of asymmetries, as induced by artificial accelerations that take into account local site conditions. The first step is to model seismic waves propagating through complex geological profiles so as to recover artificial acceleration time histories at the surface of the ground. Next, we focus on the dynamic behavior of two common types of multi-storey buildings that comprise the modern building stock in Greece. These are modeled using finite elements and their dynamic response is computed for base motions in the form of artificial accelerograms and of recorded earthquake signals. The purpose is to compare the results of time-history analyses with the dynamic response spectrum method prescribed by the Greek National Earthquake Code, especially in the case where the buildings exhibit nonlinear material behavior.
