Abstract In this study, a buckling restrained steel plate shear wall (BRSPSW) system, consisting of a steel plate linked to frame elements using a double-sides connection bolt/weld and sandwiched by autoclaved lightweight concrete (ALC) panels, was designed to resist the lateral load. Concrete-filled steel tubes (CFTs) and H-section beams were adopted to build the vertical and horizontal frame elements. Three single-bay, two-floor specimens were tested under lateral cyclic load. Besides, this study offered an eco-friendly and sustainable application for recycled aggregate concrete (RAC) as concrete infills. The hysteretic load–displacement response associated with failure patterns was deeply reported and analyzed. The three tested specimens were evaluated based on characteristic capacities. The experimental outcomes demonstrated that all specimens have excellent cyclic performance, and buckling of the steel plates was significantly reduced using bolts connection. Although yield-bearing capacity and stiffness with weld connection were relatively higher than with bolt connection, the peak-bearing capacity was almost the same with bolt or weld. In addition, the ductility, energy consumption, and displacement characteristics were improved using bolts compared with weld. Finite element (FE) models were generated and verified to analyze out-of-displacement and equivalent plastic strain. Based on validated FE models, parametric analyses were performed to examine the impact of five crucial parameters on characteristic capacities. The parametric studies presented considerable indications for the seismic behavior of BRSPSWs. The findings of this study serve as a valuable point of reference for the implementation of engineering applications.
