Abstract: - Steel Plate Shear Wall is commonly employed as a principal system to resist lateral loads due to
wind or earthquake forces. An accurate model for SPSW needs to consider the effect of all components for
analysis such as foundation and subsoil. One of most important aspects of structural analysis is soil-structure
interaction (SSI). Such interaction may alter the dynamic characteristics of structures and consequently may be
beneficial or detrimental to the performance of structures. This investigation is aimed to evaluate the effect of
soil-structure interaction on seismic response of a typical multi-story SPSW designed according to AISC
requirements. In this procedure, a time-direct method is used in which the unbounded soil is modeled by couple
finite-infinite elements. To investigate the effects of SSI the following types of analysis are performed: in the
first type, the structure is analyzed without subsoil (fixed base) and in the second type, analysis is carried out
for the same structure with consideration of soil-structure interaction (flexible-base). Finally, the results of
analysis with and without SSI effects are compared.
Key-Words: - Steel Plate Shear Wall, Soil Structure Interaction, seismic response, dynamic analysis
