摘要
分析了K形偏心支撑钢框架中耗能梁段的受力特性,利用非线性有限元程序探讨了耗能梁段长度对K形偏心支撑钢框架刚度、延性及耗能性能的影响,提出了初步设计时耗能梁段长度的取值范围。
Based on presenting the stress properties of the link beams in K-type eccentrically braced frames, the effect of link beam length on stiffness, ductility and energy consumption capacity are analyzed by using the 3D nonlinear finite element method. At last, the design criteria of length are proposed.
