摘　　要：Y型偏心支撑钢框架是一种偏心抗震耗能的结构形式。采用曲壳单元和梁单元相结合的非线性有限元分析模型,自编计算程序,分析了Y型偏心支撑钢框架在循环荷载作用下的滞回性能,提出了相应的抗震设计对策和建议。Y-eccentrically braced steel frame is the steel structure of eccentrically braced steel frames with well seismicresistance and energy-dissipation. A new analytical model which includes degenerate shell element applied to link beams with large deformation and plastic deformation and beams element applied to other parts of structure is used for analyzing Y-eccentrically braced steel frame＇s energy-dissipation behavior. Computer program is complied and suggestions on seismic design are presented.
