Abstract:
为了解近海大气环境下低矮RC 剪力墙的抗震性能,采用人工气候实验室对6 片剪跨比1.0 的低矮RC 剪力墙试件进 行模拟近海大气环境腐蚀试验,进而对其进行拟静力试验,得到不同轴压比和不同锈胀裂缝宽度下腐蚀试件的滞回曲线,绘 制出各个试件的骨架曲线,分析轴压比和锈胀裂缝宽度对腐蚀试件强度、刚度、延性、耗能能力等抗震性能指标的影响.结果表 明: 随轴压比增加,腐蚀试件的承载力和刚度不断提高,而延性和变形恢复能力却降低,表明在近海大气环境下对低矮RC 剪 力墙进行抗震设计时需要严格控制其轴压比; 随锈胀裂缝宽度的增加,试件的开裂荷载和峰值荷载不断降低,刚度、延性和耗 能能力均变差,当遭受腐蚀较为严重时,脆性破坏更为显著,说明在近海大气环境下低矮RC 剪力墙内部钢筋锈蚀越来越严 重,抗震性能越来越差.
