Abstract

Abstract

A quasi-static loading test was conducted on four full-scaled models of prefabricated steel-concrete composite tube (SRCT) shear walls to evaluate the seismic performance. The test results were analyzed in terms of failure mode, bearing capacity, hysteretic curves, ductility, stiffness degradation and energy dissipation capacity. The results showed that the SRCT shear wall had high bearing capacity, stiffness, ductility and energy dissipation capacity. As the thickness of the steel plate increased, the failure mode of SRCT shear wall changed from steel plate yielding to weld failure. Measures should be taken to ensure the welding quality of U-shaped steel and steel plates to achieve the design failure mode. The average value of the yield displacement angle of the specimens was 0.005 rad, and the average ultimate displacement angle was 0.013 rad, indicating that the deformation capacity of SRCT shear wall was higher than the specification limit. In the range of 200-250 mm spacing between stud-tie bars, properly reducing the spacing between stud-tie bars could improve the ductility and energy dissipation capacity of the shear wall.
