The Effect of Near-Fault Earthquake on Seismic Behavior of Concrete Buildings

Abstract

Due to losses and damages incurred by earthquake in seismic countries, necessity of design of earthquake- resistant structures seems inevitable. For design of a building to resist against earthquake, it is necessary to have comprehensive information about the behavior of building against forces resulted from earthquake. It must be noted that following terms and conditions of seismic design regulations do not ensure the resistance of buildings against seismic forces. For this reason, behavior of structures must be taken into account generally and accurately. In this study, effect of near-fault earthquakes on plasticity of the concrete buildings will be studied in accordance with regulation 2800. For this end, three near-fault earthquakes were selected and matched with Seismo Signal software according to regulations and then, the effect of these earthquakes on three 5, 10 and 15-storey concrete buildings is analyzed.
