摘要
As the Iranian seismic code does not address the soil-structure interaction (SSI) explicitly, the effects of SSI on RC-MRFs are studied using the direct method Four types of structures on three types of soils, with and without the soil interaction, are modeled and subjected to different earthquake records. The results led to a criterion indicating that considering SSI in seismic design, for buildings higher than three and seven stories on soil with V-s < 175 m/s and 175 <V-s <375 m/s, respectively, is essential A simplified procedure has been presented, on the basis that lateral displacement increments could be applied to the fixed-base models using simple factors (C) 2010 Elsevier Ltd All rights reserved
