摘　　要：由于种种原因,我国对钢结构震害分析以及震损加固的研究不够深入,本文从钢结构的震害分析入手,总结了钢结构震损加固的原则和方法,强调除了提高结构强度和刚度外,还要从增大钢结构在往复荷载作用下的塑性变形能力和耗能能力以及减小地震作用方面全面考虑。For various reasons,the damage analysis and study of seismic strengthening of e arthquake damage for steel structure are not deep enough in China.Based on seism ic damage of steel structure,seismic strengthening principle and methods were c oncluded in this paper.Studies show that the principle and methods are not only aiming at improving bearing capacity and stiffness,but also improving the plas tic deformation and energy dissipation capacity,and reducing earthquake response.
