Abstract :
One of the effective factors in the designing process of buildings is how to control and manage the seismic force to achieve the optimal seismic resistance while maintaining proper ductility. In this regard, the application of various bracing systems in the construction of high-rise buildings, such as steel and concrete shear walls is a common solution. Therefore, in this research, once considering the soil-structure interaction and again without considering the impact of this interaction on two 10 and 15-story structures, different models of ABAQUS software were presented in the presence of steel and concrete shear walls. The nonlinear analytical method was investigated. For this purpose, by modeling the structures mentioned in the software, the effect of using steel and concrete shear walls was analyzed in terms of the impact of soil-structure interaction and without it. The results of modeling for 10-story structures showed that the performance of the structure with steel shear wall is better than concrete shear wall. In addition, the results obtained for the 15-story structure showed that the performance of this structure with steel shear wall was better than concrete shear wall. In general, the results present that the steel shear wall exhibits better behavior than the concrete shear wall. In general, it was found that by taking into account the soil-structure interaction in the modeling performed for both types of structures, the outputs are closer to reality.
