【摘要】 基于改进的结构模型化方法和节点内梁纵筋粘接滑移滞回模型 ,对两榀平面框架在典型地震输入下的弹塑性动力反应进行了分析。通过将考虑中间节点内梁纵筋粘结滑移的地震反应与不考虑梁筋滑移的反应结果进行对比 ,从框架的整体反应、梁柱屈服特征以及梁刚度滞变方式等方面讨论了在梁柱组合体试件的抗震性能试验中经常出现的节点内梁筋滑移对框架弹塑性动力反应的影响。结合已有研究结果 ,还分析了节点内梁筋滑移对柱受力性能以及中间层节点的弯矩平衡方式的影响。更多还原

【Abstract】 The elastoplastic dynamic responses of two frames for input of a typical earthquake wave are analyzed based on the modified method for modeling structure and hysteretic model of bond-slippage of steel bar in beam.The seismic responses of frame with no considering bond-slippage of steel bar in nodes are compared with the nonlinear dynamic responses considering bond-slippage of steel bar in nodes.Influence of bond-slippage of steel bar in nodes,which usually occur in test of the seismic performance,on the nonlinear dynamic responses of frames is discussed.Concerning the obtained researchful results,influence of bond-slippage of steel bar in nodes on stressed behavior of columns and moment equilibrium mode in nodes of the middle layer are analyzed as well.更多还原
