对既有建筑结构采用碳纤维布进行加固可以提高结构的抗震能力。结合某工程实例,介绍结构加固改造方案的确定,碳纤维布抗震加固柱的设计及计算加固前后框架柱轴压比的变化。结果显示:碳纤维布加固能够有效地改善框架柱的抗震性能,加固工程的效果也满足使用要求。
The use of carbon fiber cloth to reinforce the existing building structure can improve the seismic capacity of the structure. Combined with an engineering example, the paper introduces the confirmation of the structural reinforcement and reconstruction scheme, the design of the CFRP column and the calculation of the axial compression ratio of the frame column before and after reinforcement. The results show that the CFRP reinforcement can effectively improve the seismic performance of the frame column and the effect of the reinforcement project also meets the requirements.
