变刚度连接装配式剪力墙的抗震性能试验
Seismic Performance Test of Prefabricated Shear Walls with Variable Stiffness Connection
摘要
Abstract
Two types of shear walls with variable stiffness connections using limited-slip bolts and blocking frames were designed.Quasi-static compression-shear tests were conducted to investigate the influence of this connection method on seismic performance.The results show that both variable stiffness connection designs effectively achieve segmented working mechanisms.The hysteretic curves exhibit spindle shapes,and demonstrate excellent overall seismic performance.Compared to traditional corrugated steel plate shear walls,the variable stiffness shear walls with limited-slip bolts and blocking frames show a 47%increase in bearing capacity at an inter-story drift angle of 2%.The variable stiffness design using only blocking frames displays a hilly-shaped"double peak"phenomenon with secondary bearing capacity recovery after gradual degradation,resulting in more stable energy dissipation performance.At an inter-story drift angle of 4%,the secondary bearing capacity increases by 26%.关键词
