摘要
提出了配筋混凝土砌块砌体剪力墙基于位移延性的设计方法.通过对两片不同长度的矩形配筋混凝土砌块砌体剪力墙墙肢的计算分析,研究了轴压比、高宽比、配筋率和灌孔率对墙体受力性能的影响,结果表明上述几种因素对配筋混凝土砌块砌体剪力墙结构的延性性能起着重要的作用.提出了配筋混凝土砌块砌体剪力墙结构位移延性比的计算方法和配筋混凝土砌块砌体剪力墙弹塑性层间位移角限值1/300的建议,供设计时参考.
<Abstrcat>Displacement ductility design method of reinforced concrete masonry shear walls was investigated. By analyzing two rectangular reinforced concrete masonry shear walls with different lengths, the influence of axial compression ratio, aspect ratio, reinforcement ratio and grout ratio on the shear walls was studied. The four factors affected the ductility performance of reinforced concrete masonry shear wall structures. The calculation method of the displacement ductility ratio was also investigated, and the allowable value 1/300 of elastic plastic story drift angle of reinforced concrete masonry shear wall structures was proposed for designs.
