| 摘 要： | 通过对具有不同耗能梁段长度的K型偏心支撑钢框架的滞回性能与耗能梁段的耗能性能进行非线性有限元分析结果表明:随着耗能梁段长度的增加,K型偏心支撑钢框架的强度、刚度、延性和耗能性能均产生了不同程度的退化现象;耗能梁段越短,其塑性变形越大,由此而导致耗能梁段过早塑性破坏的可能性也就越大,而耗能梁段过长则抗震性能较差。最后,根据有限元模拟结果对耗能梁段的长度提出了设计建议。

| Abstract: | It was performed nonlinear finite element analysis for K shape eccentrically braced steel frames on different length of link beam.Analysis indicates that the strength,rigidity,ductility and energy-dissipation performance of K shape eccentrically braced steel frames deteriorate differently with the length increase of link beam.The shorter the link beam is,the larger plastic deformation of it,so it makes plastic collapse easily,while a long link beam has a poor cyclic behavior.At the end of this paper,suggestions on design of the length of link beam based on finite element simulation results are presented. |
