Abstract
One of the intents of this study is to demonstrate some lacking accurate results of seismic code for considering soil-foundationstructure interaction (SFSI) effects. The other objective of this study is to evaluate the effects of type of recorded motion on the response of moderately flexible building considering SFSI effects. The effects of SFSI, under plane-strain conditions, have been studied by substructure approach for buildings supported by rigid foundations on a homogeneous, isotropic and elastic half-space. 32 data motions recorded in Imperial Valley-06 (1979) earthquake are used to demonstrate some intents of this study. It can be concluded that if it is required for an analysis, research, or study to consider SFSI effects on structural response, first of all, identical recorded earthquake motions should be selected on assumed site’s soil. As shown in this study, soil shear wave velocity of site that earthquake recorded on it and the component of earthquake motion can affect structural response and damage induced by soilstructure system. To obtain as another result in this study, considering equivalent one-storey model that usually proposed by design codes or rehabilitation provisions may not have an adequately accurate result and in some cases underestimates the induced demand by earthquake motion rather than full building. In some data motions, this incoherency effect can be resulted sensible difference of base shear index. It is concluded that number of building-story, and frequency content of earthquake motion have intense role on influenced demand for buildings considering SFSI effects.
