摘要
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,分析了单斜杆偏心支撑钢框架在循环荷载作用下滞回的性能,提出了相应的抗震设计对策和建议。
Single sway rod eccentrically braced steel frames is a kind of eccentrically braced steel frames steel structure with well resistant-seismic 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 presented in this paper for analyzing single sway rod eccentrically braced steel frames energy-dissipation behavior. Computer program is complied and suggestions for seismic design are presented.
