摘　　要：针对一个柔性钢框架工业建筑结构,拟分析其设计缺陷,然后采取措施加以改进,以满足其抗震需求.首先,分析结构的薄弱环节并提出相应的补救措施;然后,计算分析不同地震作用下结构加固前后的地震反应,检验建议措施的有效性.研究结果显示,补充侧向支撑后可有效提高原始柔性钢框架结构的抗震性能.Aiming at seeking the weak positions of a flexible steel frame structure used for industrial purpose and enhancing its aseismic capacity by taking some measures,firstly,the weak positions of the steel frame structure are analyzed;and then the validity of the proposed measures is verified by using numerical simulation.The seismic response of the retrofitted structure is compared with that of the original one in simulation duration.The results obtained show that the supplementary lateral bracings can improv the aseismic performance of the initial structure significantly.
