| 摘 要： | 利用碳纤维布（CFS）对一个9层钢筋混凝土框架的底层柱进行了加固,运用有限元程序对加固前后结构的整体抗震性能进行了动力分析.分析结果表明,利用碳纤维布加固底部框架柱有助于提高框架的整体抗震性能,从而减少框架在地震作用下的最大侧移和各层间位移.

| Abstract: | Finite element dynamic analysis was carried out for a 9-story normal RC frame and a identical frame whose first floor columns were strengthened with carbon fiber sheet. The analysis results show that using carbon fiber sheet to strengthen columns of lower floors of RC frame can improve the integral seismic behavior of RC frame and reduce the maximum displacement of frame and the story drifts. |
