【 摘 要 】

Many of RC frame structures are urgently needed to be strengthened and maintained due to the increase of service life, the change of use function, and the impact of natural disasters. This paper reviews the research status of strengthening RC structures with braces; introduces the features and connection forms of joints connecting with braces; summarizes the engineering application of buckling-restrained braces, pointing out that buckling-restrained brace is an effective means to strengthen the RC frame structures with more reliable performance and broad application prospect.
