| 摘 要： | 进行了3个1∶4缩尺的四层双肢剪力墙模型抗震性能的对比试验,连梁跨高比为1.5。模型1为普通混凝土双肢剪力墙,模型2为全再生混凝土双肢剪力墙,模型3为底部两层普通混凝土、上部两层再生混凝土双肢剪力墙。分析了各双肢剪力墙的承载力、延性、刚度、滞回特性、耗能及破坏特征。结果表明:与普通混凝土双肢剪力墙相比,全再生混凝土双肢剪力墙的抗震性能略差,底部两层普通混凝土、上部两层再生混凝土的双肢剪力墙与普通混凝土双肢剪力墙抗震性能接近。建立了再生混凝土双肢剪力墙的承载力计算模型,计算结果与试验结果吻合较好。

| Abstract: | A comparative study is conducted on the seismic behaviors of three 1/4 scale RC coupled shear wall models.The span-height-ratio of lintel beam of each set is 1.5.The first model is natural concrete coupled shear wall,the second is coupled shear wall with 100% replacement of recycled aggregate and the third is coupled shear wall with variable concrete along height.Based upon the experimental study,the stiffness and its degradation,load-carrying capacity,hysteretic behavior,ductility,energy dissipation and fa... |
