  3. Abstract:
  4. Recently, the traditional strength-based design (SBD) philosophy is being replaced by more relevant displacement-based design (DBD) approach. As a main step, DBD method requires a simplified procedure to estimate the inelastic displacement demands of the structure. This step is usually done by either replacing the non-linear system by an equivalent linear system or employing the well-known concepts of inelastic design spectra. The application of different DBD procedures and their deficiencies, thus, have been the subject of numerous researches during the recent years. However, the effect of soil is usually ignored. On the other hand, it is well-known that soil affects the structural behavior through soil-structure interaction (SSI). Soil-structure interaction not only affects the linear response of structures, but also influences on inelastic displacement and ductility demands. Consequently, any rational DBD approach should also account for the effect of SSI. In this research, the steps of DBD procedures are modified in order to account for SSI. The proposed procedure is then applied to a typical example to illustrate the importance of SSI effect. Copyright © (2006) by Earthquake Engineering Research Institute
