摘要:
对5个具有不同耗能梁段长度的Y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了非线性有限元分析。研究表明:Y型偏心支撑钢框架具有良好的耗能性能和延性,耗能梁段能够充分发挥耗能和变形的作用; 耗能梁段的长度对Y型偏心支撑钢框架的强度、刚度、延性和耗能性能均产生明显的影响,耗能梁段越短,其塑性变形越大,Y型偏心支撑钢框架的承载力越高,耗能梁段过长钢框架的抗震性能越差。
Abstract:
It was performed nonlinear finite element analysis for five Y shape eccentrically braced steel frames on different length of dissipative beam part. Analysis indicates that: the energy-dissipation performance and ductility of Y shape eccentrically braced steel frames are very good; the dissipation and deformation function of dissipative beam part can be fully used; strength, rigidity, ductility and energy-dissipation performance of Y shape eccentrically braced steel frames vary with the length of dissipative beam part; the shorter the dissipative beam part is, the larger plastic deformation is and the higher bearing capacity of it is; the longer the dissipative beam part is,the weaker cyclic behavior of steel frame is.
