预制钢筋混凝土叠合剪力墙抗震性能试验研究

EXPERIMENTAL STUDY ON SEISMIC PERFORMANCE OF PRECAST LAMINATED SHEAR WALLS

  • 摘要: 为研究预制钢筋混凝土叠合剪力墙的抗震性能,对3片预制钢筋混凝土叠合剪力墙、1片现浇钢筋混凝土剪力墙进行低周反复荷载试验,对比研究了各试件的荷载-位移曲线、骨架曲线、刚度退化规律、延性性能、耗能能力和破坏形态等,探讨了叠合墙体预制部分与现浇部分的协同工作性能,以及不同施工工艺对整体工作性能的影响。研究结果表明:1)墙体破坏以剪切破坏为主;2)预制叠合墙和现浇墙体的承载能力、破坏模式、抗震性能指标均相近;3)预制试件的预制面与现浇面交接处未出现竖向劈裂裂缝,受力变形基本同步,协同工作性能良好;4)不同施工工艺对叠合墙的承载和变形性能无明显影响。

     

    Abstract: Cyclic loading tests of three integral precast laminated reinforced concrete shear walls and one conventional reinforced concrete shear wall were conducted to study the seismic performance of integral precast laminated shear walls. The hysteretic loops, skeleton curves, rigidity degradation processes, energy dissipation, ductility and failure patterns of the test specimens were investigated. The cooperative work performance of the precast and cast-in-situ parts of the laminated walls and the influence of different construction techniques on the shear wall's seismic performance are discussed. The test results indicate that: 1) the main failure mode of the specimens is shear failure; 2) the bearing capability, failure pattern and seismic performance of precast laminated shear walls are similar to cast-in-situ walls; 3) there is no vertical split crack found at the joint surface between the precast part and cast-in-situ part of the wall, showing that these two parts are working in coordination; 4) different construction techniques have no significant influence on the bearing capacity and deformation behavior of the laminated shear walls.
