【摘要】：为综合评价现浇剪力墙预制框架半装配式框架-剪力墙结构的抗震性能,设计制作了2榀1∶2的2层2跨混凝土框架-剪力墙结构模型试件,并对其进行了低周反复荷载试验.对比研究了这2榀试件的破坏机制、破坏过程、滞回性能、位移延性和耗能能力等抗震特性.试验结果表明,半装配试件与现浇试件具有相近的开裂位移、裂缝开展形态、破坏模式、耗能能力和侧向承载能力,但半装配试件的延性略低,在不同承载状态下的水平荷载也略低.现浇剪力墙预制框架半装配式框架-剪力墙结构的整体性较好,在地震中具有可靠的抗倒塌能力.
[Abstract]:In order to comprehensively evaluate the seismic performance of the semi assembled frame shear wall structure of cast in situ shear wall, 2 specimens of 1: 2 and 2 span concrete frame shear wall structure are designed and manufactured, and their low cyclic loading tests are carried out. The failure mechanism, failure process, hysteretic behavior, displacement ductility and ductility of the 2 specimens are compared and studied. The test results show that the semi assembled specimens have similar cracking displacements, fracture patterns, failure modes, energy dissipation capacity and lateral bearing capacity, but the ductility of semi assembled specimens is slightly lower and the horizontal load is slightly lower in different loading conditions. The semi assembled frame of cast-in-place shear wall prefabricated frame is a semi assembled frame. The shear wall structure has good integrity and reliable collapse resistance in earthquakes.
