Analysis of Reinforcement Effect for Buckling-restrained Braces and Traditional Reinforcement Methods

将减震技术中的屈曲约束支撑技术应用到既有建筑房屋加固改造中,并与传统加固方法进行对比分析,探讨屈曲约束支撑在结构抗震加固设计中的优势。研究结果表明,使用屈曲约束支撑加固后可有效增加结构阻尼及延性,地震作用下结构抗震性能指标能较好地满足规范要求,实现提高抗震性能等级的目标。

In this paper,the buckling-restrained braces technology is applied to the reinforcement and transformation of existing building,and compares with traditional reinforcement method,the advantages of buckling-restrained braces in structural seismic reinforcement design are discussed.The research results show that the damping and ductility of the structure can be effectively increased by using buckling-restrained braces.The seismic performance index of the structure under earthquake can meet the requirements of the code and achieve the goal of improving the seismic performance level.
