摘要
Y型偏心支撑钢框架具有很好的抗震耗能能力。采用梁单元与壳单元相结合的非线性有限元分析模型,对Y型偏心支撑钢框架进行弹塑性时程分析,研究耗能梁段的长度和腹板高厚比的变化对结构抗震性能的影响,提出了相应的抗震设计建议。
The Y-eccentrically braced steel frame has excellent seismic-resistance and energy-dissipation. Through the finite element model combing both the shell element and beam element, the paper makes an elasticplastic time history analysis of the seismic behavior of the Y-eccentrically braced steel frame to study how the change of parameters such as length of link beam and height-thickness ratio of web influences the properties of structural seismic-resistance. Some related seismic resistance designs are suggested.
