Abstract：In order to improve the precision of numerical simulation of low reinforced concrete shear wall panel and refine the constitutive theory of concrete under cyclic shear loading, a total of six reinforced concrete shear wall panels were tested under cyclic shear. The effects of reinforcement ratio and the orientation of steel bars on hysteretic behavior and cumulative hysteretic energy dissipation capacity of the reinforced concrete shear wall panels were investigated. The hysteretic curves, skeleton curves, ductility, stiffness degradation, and cumulative hysteretic energy dissipation capacity were obtained. Test results reveal that the shear failure mode occurred for all of the test specimens. The reinforcement ratio had a certain effect on the shear capacity of reinforced concrete shear wall panel, but hardly had an effect on the ultimate deformation capacity. The orientation of steel bars had a remarkable influence on the hysteretic curve of reinforced concrete shear wall panel. The smaller the angle between the distributed steel bars and the inclined shear cracks is, the more plump the hysteretic curve is, and the larger those parameters such as the cumulative plastic shear ratio, cumulative ductility ratio, equivalent viscous damping ratio and cumulative hysteretic energy dissipation ratio shall be, but the smaller the initial shear stiffness shall be. The test results in the work can be referred for further improving the constitutive theory of concrete.
