Abstract
Precast shear wall is an important structural form of building industrialization and housing industrialization. In order to improve the seismic performance of precast shear wall, the reinforced tenon is presented to improve the shear performance of precast shear wall joints. In order to grasp the further difference of mechanical properties of reinforced tenon precast shear wall under different axial compression ratios, the low cyclic reversed loading tests were carried out on a cast-in-situ shear wall specimen and two reinforced tenon precast shear wall specimens with different axial compression ratios respectively. According to the test results, the hysteresis characteristics, bearing capacity, steel strain, energy dissipation capacity, rigidity degeneration and other seismic performance parameters of the three specimens were analyzed. The test results show that the failure modes of the three specimens were same, which was compression-bending failure. Connection form of reinforced tenon has good shear resistance. The reinforced tenon precast shear wall with the larger axial compression ratio has the worse ductility, the higher bearing capacity and stronger the rigidity.
