Study of influences of partial plate-frame connection on the cyclic behavior and performance of LYP corrugated SPSW system
Abstract
The application of steel plate shear walls (SPSWs) as a lateral load-bearing system in new and retrofit construction has grown rapidly in recent years. Advantages such as excellent ductility and high energy dissipation capacity make such a structural system suitable for construction in low- to high-seismic regions. Early design approaches typically used flat web-plates with conventional steel which was fully attached to the surrounding frame components. Unstiffened infill plates suffer from low buckling capacity and the designer is compelled to provide longitudinal and transverse stiffeners to improve the stability performance. This results in increased construction costs. The application of corrugated web-plate with higher buckling capacity combined with the merit of low yield point (LYP) steel material and partial plate-frame connection can lead to the design of a system with desirable structural performance. Such novel and promising steel shear wall systems have not been investigated thoroughly and systematically. This study investigates the monotonic and cyclic behaviors of two-story shear walls with curved-corrugated, LYP steel, and partially connected web-plates. A series of finite element analyses are conducted to evaluate the effectiveness of using curved, LYP steel and partially connected infill plates for improving the performance of the shear wall system. This research demonstrates how the employment of curved-corrugated and partially connected infill plates made of LYP steel material with relatively larger thickness can result in the design of cost-effective and high-performing steel shear walls with considerable stiffening and damping capabilities.
