Experimental research on seismic performance of cantilever structure of shear wall

Abstract

When the shear wall and two orthogonal frame beams cannot intersect, a special steel reinforced concrete (SRC) cantilever structure was designed. The cyclic load test on 1:2 scale model was completed and the hysteretic loop, the ductility coefficient, the strength reduction coefficient and the equivalent viscous damping coefficient were obtained, showing that the SRC cantilever structure has agreeable seismic performance. The cracks generated by cyclic load are obliquely intersected with the frame beam, demonstrating that the SRC cantilever structure fails due to combined shear, bending and torsion.
