| 摘 要： | 对一榀损伤方钢管混凝土框架加固后在低周反复荷载作用下进行试验,对试验结果及框架的滞回性能、破坏特征、延性等抗震性能做了分析,并将试验结果与该框架在无初始损伤时的低周反复加载试验结果进行了比较。在此基础上,对损伤方钢管混凝土框架的加固提出建议。试验结果表明,本文中的加固方案可行,损伤框架加固后仍具有良好的抗震性能。

| Abstract: | Strengthening and upgrading of existing damaged concrete-filled steel tubular frame was dealt.The seismic behavior of the strengthened frame was investigated experimentally under low-cycle reversed loading,including the hysteretic behavior,the failure characteristics,the ductility characteristics and so on.and the experimental results were contrasted between the strengthened frame and the former one.Based on the test results,strengthening and upgrading methods for concrete-filled steel tubular frame were proposed,which may be used for practical design and investigation.The test results indicate that the strengthening frame still have good seismic behavior and the strengthening design is feasible. |
