内埋管状内模低矮剪力墙受剪承载力分析

Analysis on shear bearing capacity of low-rise shear wall with embedded hollow pipe filler

借鉴现浇混凝土空心楼盖结构和开设竖向缝槽低矮剪力墙的技术,提出一种新型的抗侧力结构——内埋管状内模钢筋混凝土低矮剪力墙.对3片内埋管状内模低矮剪力墙、1片开设竖向缝槽低矮剪力墙和1片普通低矮剪力墙试件在低周反复水平荷载作用下进行抗震性能试验,并根据内埋管状内模低矮剪力墙的破坏形态和试验结果,建立了内埋管状内模低矮剪力墙受剪承载力计算公式,计算结果与试验结果一致,为工程设计提供参考.

Reference to cast-in-situ concrete hollow floor structure and low-rise shear wall with vertical seams technology, a new type of lateral force resistant structure the low-rise shear wall with hollow pipe embedded is put forward. The experimental study of seismic behavior on 3 low rise shear wall with embedded hollow pipe filler, 1 slit low-rise shear wall and 1 ordinary low-rise shear wall subjected to low-cyclic load are carried out. According to its failure features and experimental results, the calculation formula of shear bearing capacity is established and the calculation results are in good agreement with the test results, which provides references for engineering design.
