A total of 15 squat reinforced concrete (RC) shear walls (12 of them were reinforced with high strength reinforcement of HRB600 [Grade 600 MPa] and the remaining 3 with normal grade reinforcement of HRB400 [Grade 400 MPa]) have been tested under the cyclic loading. The influencing parameters considered in the test specimens include the grade of reinforcement, axial load ratio, types of cross section, and reinforcement ratio. The seismic performances of the squat RC shear walls have been studied using the test results based on the failure mode, hysteretic behaviors, peak shear strength, deformation capacity, secant stiffness degradation, and inelastic energy dissipation capacity. The test results reveal that the failure modes of the walls with HRB600 steel bars are similar to those walls with HRB400 reinforcement. The walls with high strength reinforcement tend to achieve a larger ultimate deformation but …
