In addition to earthquakes, the behavior of soil and its effects on seismic responses of structure, also known as Soil-Structure Interaction (SSI), make this problem more complicated. For this purpose, today, many investigations are focusing on soil role in seismic behavior of structures. In this study, the seismic behavior of steel structures with various heights under the SSI effect have been studied. For this purpose, three steel structures including 9, 15 and 20 story frames were modeled using Opensees. Besides, their seismic behaviors under different ba se conditions including fixed base and on three different types of soil (B, C and D) under 11 bedrock earthquakes were also investigated using the direct method. The responses in two terms including story shear and story drift were also investigated. 1. Introduction The prediction of seismic behavior of structures during earthquakes can significantly reduce fatalities and financial damages. Many efforts have been conducted by structural and earthquake engineers in order to find appropriate ways to enhance this knowledge. However, it is difficult to predict these behaviors due to the complexities of the nature of earthquakes. Aside from earthquakes, one of .
