Seismic Experiment and Load-carrying Capacity Calculation of RC Shear Wall Joint With Bi-directional Single Row of Steel Bars

In order to study on the seismic performance of joint of coupling wall-column and coupling wall-beam in the RC shear wall with bi-directional single row of steel bars,a low-frequency quasi-static cyclic loading test of four joint models with different details of seismic design is carried out. The load-carrying capacity,ductility, stiffness,energy dissipation and failure phenomena of each specimen are analyzed and calculative formulas of the load-carrying capacity is established,and the calculating results agree well with the experimental results. Experiments indicate that the joint with reasonal detailing reinforcement is able to satisfy the requirements of seismic design for multistory residence building.
