Abstract

Abstract

The horizontal relative slip of the precast shear wall joints has a negative impact on the seismic performance of the precast shear wall.In order to improve the mechanical properties of the precast shear wall joints, a new type of precast shear wall with large-size reinforced tenon to resist the shear force of the joints and the longitudinal connecting steel bars to bear tensile and compressive stress and yield energy dissipation was proposed.In order to investigate the seismic performance of reinforced tenon precast low-rise shear walls, two reinforced tenon precast low-rise shear walls with aspect ratio of 1.76 and 1.5 were tested under quasi-static loading.The crack development law and failure mode of the specimens were observed, and the hysteresis curve, skeleton curve, bearing capacity, stiffness degradation, ductility, energy dissipation capacity, steel bar strain and joint connection performance were analyzed.The results showed that the failure modes of the two specimens were compressive bending failure at the bottom joint of the wall, but there was no large shear slip at the joint interface, which showed a good shear bearing capacity.The mechanical properties such as initial stiffness, energy dissipation capacity and ductility of the wall could reach the level of ‘equivalent cast-in-situ’.At the same time, the specimens with lower aspect ratio showed better seismic performance.
