“…Other research studies have studied the seismic behavior of shear walls with diagonal reinforcement, and the results show that oblique reinforcement could improve the deformation capacity of the shear wall, slow down the sti ness degradation, and e ectively avoid shear failure [7,8]. Experimental research on shear walls with concealed bracings was also conducted, and the results show that owing to the existence of bracings, the cracks in the concrete were fully developed; the overall sti ness decreased slowly throughout the test, which improved the seismic performance of the shear walls [9][10][11]. e seismic behavior of composite shear walls is studied by authors of reference [12,13], and the test results indicate that the composite shear walls with embedded steel plate reinforcement can enhance the advantages of steel and concrete combination, improve the bearing capacity and lateral stiffness of the shear wall, and reduce the section area of the shear wall.…”

In this paper, a new reinforcement scheme is proposed to improve the seismic performance of low-rise shear walls. The new system combines the advantages of slotted and composite shear walls to exhibit a high bearing capacity and good deformation performance. Two low-cycle repeated loading tests with different forms of shear walls were conducted to accurately understand its seismic performance. Seismic performance indexes, such as failure mode, bearing capacity, hysteresis curve, stiffness degradation, and energy dissipation capacity, of the new shear wall under the low-cycle reciprocating load were obtained to verify its reliability. The results show that the newly reinforced shear wall has two clear seismic defense lines. Its deformation and energy-dissipation capacities and lateral stiffness stability are greatly improved compared with traditional low-rise shear walls. Thus, the proposed method can provide a new means for enhancing the seismic performance of shear walls.
