Abstract:
The shear-slip is easy to occur at the bottom construction joint of the shear wall with single row of steel bars when it is subjected to horizontal earthquake action under low axial compression ratio. The shear-slip will decrease the energy dissipation capacity of the shear wall. The phenomenon can be avoided successfully by setting some inclined reinforcement on the bottom of the shear wall. In order to investigate the effect of inclined reinforcement, placed in the shear wall limbs and coupling beam, on the failure mechanism and seismic behavior of RC coupled shear walls with single row of steel bars, three 1/2 scaled models subjected to low-cycle reversed loading were tested. Comparative analysis on failure modes, hysteresis property, load-carrying capacity, ductility, stiffness and energy dissipation capacity between specimens with inclined reinforcement and normal specimen was carried out. The results show that when the total amount of reinforcement of the shear wall limbs is constant, setting inclined reinforcement on the bottom of shear wall limbs not only can increase the ductility and energy dissipation of shear wall, but also has an influence on its failure mechanism. When the amount of web reinforcement of the shear wall limbs is constant, adding inclined reinforcement on the bottom of shear wall limbs and coupling beam will obviously improve the ductility and energy dissipation capacity of the shear wall. © 2016, Editorial Office of Journal of Building Structures.
