不同截面异形柱梁柱节点抗震性能分析
|
摘要
通过研究不同截面形式异形柱梁柱节点,并引入135°L形异形柱梁柱节点进行抗震性能数值模拟对比分析,研究了不同截面形式异形柱梁柱节点的滞回曲线、延性系数、极限荷载及骨架曲线等因素对抗震性能的影响。结果表明:异形柱梁柱节点的延性、耗能能力与柱截面形式有关;双向荷载情况下,异形柱梁柱节点的屈服荷载、极限荷载及破坏荷载均较单向荷载情况下小;135°L形异形柱梁柱节点的位移延性系数较小,耗能能力弱于其他截面形式节点,在结构设计中应适当加强配筋。
By studying the beam-columns joints of special-shaped columns with different section forms,and introducing the beam-columns joints of L form with 135° special-shaped column,the influence of hysteresis curve,ductility factor,ultimate load and skeleton curve on the aseismic ability of the beam-column joints of special-shaped columns with different section was researched.The results indicate that the ductility and ability of energy dissipation of the beam-column joints of special-shaped columns are related to the section form of columns.The yield load,ultimate load and failure load of the beam-column joint of special-shaped columns in two-way load condition are smaller than that in one-way load condition.The displacement ductility coefficient and ability of energy dissipation of beam-column joint of L form with 135° specialshaped column are smaller than that of columns with other section forms.So the appropriate reinforcement should be strengthened during the structural design process.
