| 摘 要： | 为了研究再生骨料对双肢剪力墙性能的影响,本文对4个1∶4缩尺的4层双肢剪力墙进行了低周反复荷载试验,各模型连梁跨高比均为1.0.模型1为普通混凝土双肢剪力墙,模型2、3分别为再生骨料取代率为50%、100%的再生混凝土双肢剪力墙,模型4为带暗支撑全再生混凝土双肢剪力墙.分析了各双肢剪力墙的抗震性能.结果表明:与普通混凝土双肢剪力墙相比,再生混凝土双肢剪力墙的抗震性能略差,且再生混凝土双肢剪力墙的抗震性能随再生骨料掺量的增加而下降;加配暗支撑可以使再生混凝土双肢剪力墙的抗震性能有效提高.建立了再生混凝土双肢剪力墙的承载力计算式,计算结果与试验结果吻合较好.

| Abstract: | In order to know the influence of recycled aggregate on property of seismic performance of the coupled recycled concrete shear wall,a low-frequency quasi-static cyclic loading experimental for four 1/4 scale RC coupled shear wall models with the 1.0 span-height-ratio of lintel beam was carried out.The first model was common concrete coupled shear wall.The replacement of recycled aggregate for the second model was 50% and the third was 100%.The forth was recycled concrete coupled shear wall with concealed br... |
