Abstract

Steel shear walls have different systems and models, each of which has different fields for investigation and design. Steel shear walls can be classified in categories with or without opening, and each of these models can be placed in steel shear wall systems with or without stiffeners. The steel shear wall system can also be implemented in composite. In this research, it is intended to improve the seismic behavior of this system by adding yielding steel dampers, which is discussed below. For this reason, in this research, it is intended to "Cyclic analysis of steel shear walls with peripheral yielding dampers" in order to evaluate the performance of bending steel frames with steel shear wall system under nonlinear dynamic load. In this research, the studied samples were numerically loaded under cyclic load analysis using ABAQUS v-21 software, and the results of stress, strain and displacement values at the moment of maximum load and at the end of loading were compared with each other for the samples in question, and after evaluating the results of the samples from their analysis, the best performance was determined. As seen, the use of Amo's peripheral yielding dampers on the wall plate when the peripheral dampers are only connected to the beams has led to improved performance and reduced displacement outside the wall plane, increased elastic displacement of the frame, reduced stiffness of the frame and reduced drift of the frame. On the other hand, the use of peripheral yielding dampers in line with the wall plate when the peripheral dampers are only connected to the beams has led to improved performance and increased elastic and plastic stiffness of the frame, increased force absorption in the elastic and plastic area of the frame during the load process
