| 摘 要： | 现有结构弹塑性分析软件大部分都是假定钢筋混凝土框架节点完全刚性,不发生任何损伤和破坏.但对于某些工程而言,当遭遇中震或大震时,节点处梁筋的粘结滑移及节点开裂或破坏就变得在所难免,这就不符合节点刚性的假定.本文根据已有的实验结果和结构理论分析了相应的节点变形,最后探索性地提出了一种考虑节点变形的RC杆件单元模型概念,以供在混凝土框架结构弹塑性地震反应分析中参考.

| Abstract: | Most of the nonlinear dynamic programs assume infinitely rigid beam-column joints in concrete frames.Some reinforced concrete frames may have inadequate joint reinforcement and detailing for some reasons.This may result in shear failure at the joints.At last a RC frame model with consideration for beam-column joints deformation is proposed in the paper.It can be applied to the analysis of nonlinear seismic response of RC frame structures. |

| Keywords: | beam-column joints deformation shear deformation bar bond slip RC frame model |
