Studying the effect of thickness, diameter, and arrangement of hemispherical ridges in steel shear walls

Steel shear walls are usually made in two types, hardened and unhardened. All hardened types are more suitable for seismic performance and operational issues. But due to the presence of many hardeners and implementation details, it takes a lot of time and money to make them. Therefore, the idea of corrugated steel shear walls as a replacement for Hardened shear walls has been proposed. These sheets are expected to have Inherent out-of-plane hardness, and high buckling resistance, and are ultimately functional, similar to hardened shear walls. In this research, steel shear walls it has a flat panel and hemispherical protrusions used to evaluate the energy absorption capacity Different models were used, and the amount of formability and energy loss of steel shear wall with interest the above parameters have been checked from ABAQUS finite element software. For this purpose ۸ the sample of steel shear wall with hemispherical protrusion was modeled in ABAQUS software a sample of it as a control sample for comparison and verification with the laboratory results of the case A study was done that showed good accuracy for verification. Then the samples were made were subjected to cyclic loading according to the ATC۲۴ regulations.Steel shear walls are usually made in two types, hardened and unhardened.
