Abstract:
施工缝的存在会在一定程度上影响剪力墙的性能,为研究施工缝对钢筋混凝土剪力墙抗震性能的影响,对整浇和带施工缝两种剪力墙试件进行拟静力试验。通过对比分析施工缝对剪力墙破坏过程的影响,并从滞回曲线、承载能力、变形能力、耗能、刚度退化和破坏过程等方面分析施工缝对剪力墙抗震性能的影响。研究结果表明,同等条件下带缝剪力墙与整浇剪力墙的最后破坏形态基本一致,但是裂缝发展过程明显不同,带缝试件初始裂缝及贯通裂缝出现在施工缝处,而整浇试件的初始裂缝及贯通裂缝出现位置比较随机。轴压比较小时,整浇试件的承载力和耗能比带缝试件高;轴压比较大时,轴向力抵消了施工缝的不利影响,带缝试件的承载力和耗能比整浇试件的高;整浇试件的延性和刚度退化均比带缝试件的小;配筋率提高使带缝试件的承载力提高、耗能增大,但对刚度的影响较小;轴压比增大使带缝试件的延性降低、刚度退化变快。
