Seismic Simulation Analysis of a New Type of Prefabricated Shear Wall under Tensile Conditions
Cold joints in prefabricated shear wall structures have always been the weak point of this type of structure,which has a great impact on the seismic performance of the structure,for this reason,the paper proposes a new type of improved overhead connection prefabricated shear wall structure.To study the seismic performance of this new overhead connection prefabricated shear wall structure,five models with different connection modes are designed to compare the seismic performance of the prefabricated shear wall under axial tension conditions,and the hysteresis curve,stiffness curve,energy dissipation capacity,and damage cloud of specimens with different connection modes are analyzed in terms of the numerical simulation results.The results show that when the prefabricated shear wall structure with improved overhead connection is under axial tensile conditions,the built-in angle steel shear-resistant connectors can effectively prevent the cold joints from developing into cracks,improve the shear capacity at the cold joints,effectively improve the energy dissipation capacity of the members,and the area of the plastic zone is obviously increased,and the seismic performance is increased.
