Cyclic performance of four-layer flat-corrugated steel shear walls using low-yield-point steel plate

Steel plate shear walls (SPSWs) are mainly implemented as flat plates (FPs). However, their development has been accelerated in recent years. Recently, a new concept of utilizing corrugated and flat plates in combination with infill plates has been proposed. In this investigation, the performance of a single-story, single-span steel frame with a flat-corrugated SPSW (FCoSPSW) encompassing double-corrugated plates enclosed by FPs was explored in Abaqus during cyclic loads. Flat SPSWs (FSPSWs), single-corrugated SPSWs (CoSPSWs), and double-CoSPSWs (DCoSPSWs) were also evaluated comparatively in the present study. ASTM A36 steel was used for boundary members, and ASTM A36 and LYP100 steel were deployed for infill plates. The outcomes showed that FCoSPSWs performed better than other SPSWs. According to the findings, the hysteresis curve of FCoSPSWs was plump, while severe pinching was observed in the hysteresis curve of FSPSWs. This investigation also showed that, unlike single and double CoSPSWs, the plate corrugation angle does not significantly affect the lateral behavior of FCoSPSWs. This investigation also showed that the type of infill plate steel did not affect the strength of FCoSPSWs but increased the energy dissipation capacity.
