Cyclic test and parametric analysis of steel shear wall made of two inclined slotted infill plates

This study investigates the seismic performance of a steel shear wall (SSW) made of two inclined slotted infill plates. Despite widespread use of SSWs, conventional steel shear walls (C-SSWs) face challenges such as limited energy dissipation and vulnerability to brittle failure under seismic loading. To overcome these issues, this research investigates the cyclic behavior of the slotted steel shear wall (S-SSW) compared to the conventional one. Understanding the impact of the configuration of infill plates is essential for improving seismic behavior and safety. The necessity of this research arises from the demand for enhanced ductility and energy absorption in seismic design. The methodological approach combines experimental testing of two 1/3-scale shear wall specimens to capture their hysteretic behavior. Alongside a parametric study utilizing Abaqus software is also used to evaluate the width-to-thickness ratios of the inclined strips over the behavior of the system. The findings reveal that while S-SSW exhibits reduced initial stiffness and strength, it demonstrates a substantially higher capacity for energy dissipation, contributing to improved seismic performance. Furthermore, the results of parametric studies reveal a clear dependence of both stiffness and strength on the width-to-thickness ratio of inclined strips.
