摘要
基于结构加固存在二次受力的特性 ,对碳纤维布加固钢筋混凝土短柱在反复荷载作用下的受力性能进行了对比试验研究。探讨了二次受力对碳纤维布加固钢筋混凝土短柱的受力性能、破坏特征及破坏机理的影响。试验表明 ,采用不考虑构件二次受力特性的加固加载方案 ,会过高地评估加固构件的承载力提高值和抗震性能改善的相关指标 。
Based on the characteristic of two-stay load in the strengthening structure, a contrast experiment on behavior for reinforced concrete (RC) short column strengthened with carbon fiber sheet (CFS) under cyclic load was performed. The effects of two-stay load on the failure mode and mechanism of RC short columns strengthened with CFS are discussed. The test results indicated that the growth value of the bearing capacity and the interrelated index improving the seismic behavior were overestimated without considering characteristic of two-stay load in the strengthening structures. This will come into being disadvantage on design of the practice strengthening projects.
