  7. Abstract:
  8. There are two aspects to this research. In the first section, a numerical method is used to analyze the seismic performance of reinforced concrete frames with corrugated and flat steel shear walls as a lateral bearing system. In the second section, the seismic performance factors for reinforced concrete frames with corrugated steel shear walls (response modification factor (R), overstrength factor (Ω_0), and deflection amplification factor (C_d)) for reinforced concrete frame with corrugated steel shear walls have been determined.In the first section of this study, a three-story reinforced concrete frame with a flat steel shear wall with a scale of one to three is validated in finite element software after being subjected to cyclic loading in an experimental study. Then, the impact of steel plate type and yield stress on the initial stiffness, maximum lateral strength, and ductility of a reinforced concrete frame with a steel shear wall is investigated, taking into account three types of steel plates (flat steel plate, horizontal corrugated steel plate and vertical corrugated steel plate) and three different types of steel materials for steel shear wall.In the second section, 16 frames according to FEMA P695 recommendations have been designed and modeled in OpenSEES software, and subject them to nonlinear static analysis as well as incremental dynamic analysis, assuming a behavior factor of 7.5 for the concerned structural system.The overstrength factor is calculated using the graph obtained from nonlinear static analysis. In addition, it analyzes the accuracy of the assumed behavior factor based on the findings of incremental dynamic analysis and the instructions provided in FEMA P695. Besides, it estimates the relocation increase factor according to the same instruction
