In order to improve the space utilization rate and seismic performance of high-rise buildings, a new seismic structural system, a buckling-restrained steel plate shear wall (SPSW) with concrete-filled L-shaped built-up section tube composite frame is proposed in this study. In this composite shear wall system, the columns in the frame are
composed of hot-rolled carbon steel H-section members and carbon steel square hollow section tubes, which are connected by steel plates and filled with concrete, and the steel plate shear wall is comprised of an embedded steel plate and several pairs of cold-formed steel hat section buckling-restraining strips. In order to study the seismic performance of this new type of shear wall system, two specimens were prepared and tested subjected to the horizontal cyclic load. Test results show that the two specimens had great bearing capacity, good ductility and energy dissipation capacity.
It is indicated that the new shear wall system is reliable and effective to resist lateral forces. The finite element models were established and validated against the experimental results. Based on the parametric analysis results, the coefficient η was proposed to be taken as 0.85 to modify the PFI theory, which could be used to calculate the bearing capacity of the buckling-restrained SPSW with concrete-filled L-shaped built-up section tube composite frame.
