| 摘 要： | 为了研究再生混凝土剪力墙的动力性能,进行了3个1/3缩尺的不同再生骨料取代率的中高剪力墙模型的模拟地震振动台试验,其中1个为普通混凝土剪力墙、1个为再生粗骨料混凝土剪力墙、1个为全再生骨料混凝土剪力墙。试验过程经历了剪力墙弹性、开裂和破坏阶段,实测并比较分析了各剪力墙在不同阶段的动力特性、动力反应及破坏形态。试验结果表明:再生粗骨料混凝土中高剪力墙具有和普通混凝土剪力墙相近的抗震性能,其墙体开裂时台面加速度输入降低9.7%,其弹塑性位移角达到1/120时台面加速度输入降低5.8%,经合理设计,可用于建筑结构。

| Abstract: | To achieve the seismic performance of recycled concrete shear walls,three 1/3 scaled models with different percentage of aggregate replacement,including one natural concrete shear wall,one recycled concrete shear wall with 100% recycled coarse aggregate and one recycled concrete shear wall with 100% recycled coarse and fine aggregate,were tested on the shaking table.The testing process included elastic,cracking,and failure stages of the model structures.Dynamic characteristic and dynamic response of the str... |
