Abstract

The aim of this thesis is evaluation of the seismic performance of steel shear walls with different types of elliptical openings and (RBS). Some of the parameters investigated are the effect of geometric characteristics of elliptical openings on the strength and ductility of shear walls under dynamic loads and the determination of improvement strategies for the cyclic behavior of steel shear walls. Also, the effect of the number of these openings and the comparison of the analysis of the changes in the seismic behavior of the shear wall in different arrangements of these openings and the comparison of the shear wall with continuous web plate with the models with elliptical openings will be discussed and studied. The results of the research show that these methods increase the ductility and energy absorption and reduce the damage in the connection and column areas. Also, the results indicate that the use of low yield point steel in the web plate reduces the shear force and increases the lateral displacement and ductility of the shear walls. Furthermore, the effects of different parameters such as the size and shape of the openings and the type of connections on the behavior of steel shear walls are also investigated.
