| 摘 要： | 为了保证加固框架在抗震区应用的安全性，采用加强节点，梁端削弱的方法对震后钢管混凝土框架进行加固，为考察加固后的框架是否满足延性框架的要求，通过拟静力试验，对比分析了损伤加固框架和原框架的抗震性能．研究表明，损伤加固后的方钢管混凝土框架不仅承载能力有了大幅度的提高，并且延性系数好。满足延性框架的要求，耗能能力接近原框架，说明加固效果显著．

| Abstract: | The damaged concrete-filled rectangular tubular frame was reinforced by strengthening joints and weakening beams to improve ductility and sturdiness. To investigate the strengthening effect and ensure the safety of application in the earthquake area, the seismic behavior of the reinforced damaged frame was compared with that of the undamaged one through pseudo static test. The results show that the beating capacity of reinforced frame is obviously enhanced, the ductility coefficient is high and meets the requirement of the ductile frame, and its energy dissipation capability is similar to that of the undamaged one. Therefore, the strengthening effect is significant. |
