[摘要]屈曲約束支撐的滯回曲線飽滿,具有較好的抗震性能,用于結(jié)構(gòu)抗震加固更顯優(yōu)勢(shì)。通過對(duì)玉溪一中教學(xué)樓采用屈曲約束支撐進(jìn)行抗震加固的介紹,說明了采用屈曲約束支撐加固結(jié)構(gòu)體系的分析方法。在此基礎(chǔ)上對(duì)該加固結(jié)構(gòu)進(jìn)行反應(yīng)譜分析及時(shí)程分析。分析結(jié)果表明,加固后結(jié)構(gòu)的抗震性能得到了極大改善,結(jié)構(gòu)的抗震能力顯著提高。

Abstract: Buckling restrained braces, which have full hysteresis curves and well seismic performance, have more advantages in structural seismic reinforcement. The application of buckling restrained braces in the seismic strengthening engineering of Yuxi No.1 middle school teaching building was introduced to illustrate the analysis method of the structural system strengthened by buckling restrained braces. On this basis, response spectrum analysis and time-history analysis were carried out on the strengthened structure. Analysis results show that the seismic performance of the strengthened structure is greatly improved, and the seismic capacity is increased significantly.
Keywords:buckling restrained brace; seismic strengthening; energy dissipation; time-history analysis; seismic measure
