Abstract
One of the most important and fundamental issues that civil engineers always deal with today due to its importance is the study of the performance and behavior of structures under different conditions. In addition, in many cases, buildings are analyzed and designed separately and without considering the effect of other elements, including the foundation and soil of the infrastructure, which in many cases creates irreparable risks; Therefore, it is necessary to study and evaluate the effect of soil-structure interaction on the performance and design of buildings in order to manage the cost and time of construction projects. In this study, the performance of steel structures with concentric brace of 5, 10 and 15 floors by considering the interaction of soil structure in three different soil modes using nonlinear dynamic analysis of time history under 3 near-fault earthquakes has been done. The results show that considering the interaction of soil and structure increases the accuracy of structural responses.
