Bearing wall structures (known as tunnel form), are used in earthquake-prone areas because of their acceptable seismic performance and high construction speed. However, seismic codes didn’t specifically focus on these types of structures. As a result, the design of these types of structures are done with conventional design methods of buildings with shear walls including height restriction. In this study, a closer look at the seismic performance of tall buildings with bearing wall structure have been investigated. For this purpose, three structures of 15, 20 and 25-story with this seismic system have been modelled and examined by the help of fiber elements. Terms such as response modification factor, performance point, have been evaluated by conducting nonlinear static and dynamic analysis on these three structures. Then to complete the required studies, nonlinear time history dynamic analysis was performed to verified nonlinear static analysis.
