| Abstract: | To improve the building quality and analyze the overall seismic performance of precast hollow slabs under cyclic loading,the residual seismic performance of precast hollow slabs based on reinforcement tension and pressure transfer was studied.Different types of test pieces of the precast hollow slab without reinforcement were prepared,and the performance changes of each test piece were recorded under cyclic loading.The test results showed that,compared with the precast hollow slab with shear-compression failure,the hysteresis curve of the precast hollow slab with compression bending failure is fuller,and the safety margin of bearing capacity and seismic bearing capacity are higher.Under cyclic loading,the buckling stiffness and peak stiffness of each specimen are only 50%and 20%of the original stiffness,respectively.However,the stiffness degradation of the specimen with reinforcement tension and pressure transfer and prefabricated boundary elements is the smallest,and its residual deformation distribution and residual seismic performance are better. |
