| 摘 要： | 为了研究不同再生骨料取代率对剪力墙性能的影响,进行了4个剪跨比为1.0的低矮剪力墙的低周反复荷载试验研究,包括1个普通混凝土剪力墙和3个再生混凝土剪力墙.在试验的基础上,分析了各剪力墙的承载力、延性、刚度、滞回特征、耗能及破坏特征.研究表明:与普通混凝土剪力墙相比,再生混凝土低矮剪力墙的抗震性能略差,且随着再生骨料掺量的增加,再生混凝土剪力墙的性能呈下降趋势;暗支撑的设置能够明显改善再生混凝土低矮剪力墙的抗震性能;在一定的条件下,再生混凝土可用于一些剪力墙结构的抗震设计.

| Abstract: | In order to investigate the seismic performance of the low-rise concrete shear wall with different percent of coarse recycled aggregate replacement,a low-frequency quasi-static cyclic loading experimental study on four low-rise shear walls with shear-span ratio 1.0,including a usual concrete shear wall and three recycled aggregate concrete shear walls,was carried out.Based upon the experimental study,the load-carrying capacity,ductility,stiffness,hysteretic behavior,energy dissipation and failure phenomena ... |
