摘　　要：钢结构偏心支撑体系在国外已被广泛应用于多层钢框架中，而我国8～12层钢结构框架仍以混合型体系为主。为了推广这种体系，详细介绍了耗能梁的分类、耗能梁对偏心支撑结构的作用、多层钢框架中弯曲型耗能梁——偏心支撑钢结构体系在弹性阶段对侧移的控制及设计。分析表明，这种新型体系受力性能合理、弹性刚度好、经济性能高，适用于在多层钢框架中应用。The steel Eccentrically Braced Frames （EBFs） have been widely applied in the multi-storey steel frames. In order to promote its development in China, the classification of active link and its effect on the working performance of EBFs were discussed. The design of EBFs in multi-storey steel frames was introduced. Its stiffness of elastic stage was also analyzed. Due to the remarkable advantages of working and economic performance, the EBFs are recommended to the practical use.
