Structural Behaviour and Seismic Performance ‎Assessment of Steel Plate Shear Walls with Corrugated, ‎Perforated, and Low Yield Point Steel Web Plates
type: CreativeWork
description: Steel plate shear walls (SPSWs) employing corrugated, perforated, and low yield point (LYP) steel infill plates are investigated in this research. Such lateral load-bearing systems are used in new and retrofit construction of low- to high-rise buildings. Employment of LYP steel with low yield stress and high elongation capacity combined with the use of corrugated web-plate providing relatively higher out-of-plane stiffness and strength results in the design of a high-performing structural system. Advantages of LYP steel as the infill plate material have been demonstrated in different studies; however, the structural characteristics of LYP steel shear walls employing corrugated and perforated infill plates have not been sufficiently and systematically investigated. A comprehensive parametric study is conducted in this research in order to investigate the structural behaviour and seismic performance of corrugated- and perforated-web, LYP steel shear wall systems. Detailed investigations on the geometry of the web-plate showed that the SPSWs with curved-corrugated and perforated infill plates are good and promising structural systems, and a desirable performance can be achieved through proper design and detailing of the system components. Assessment of the stiffness, buckling behaviour, and yielding of the considered SPSW models showed that the performance of panels made of ASTM A36 steel is more or less similar to the performance of those employing LYP steel plates with greater thickness. All the panels employing LYP steel exhibited high energy dissipation capability as a result of the superior LYP steel material properties. Such models, also, possessed excellent post-buckling strength behaviour which makes them highly qualified for seismic applications. It was also demonstrated that application 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-perf…
