摘要
基于纤维模型有限单元柔度法,考虑粘结滑移效应,对钢筋混凝土结构承受单调荷载作用下进行非线性分析。考虑钢筋与混凝土之间的粘结滑移,计算出构件截面的转角和曲率,迭代过程中,在截面层次用该曲率对原来的截面曲率进行修正,计算出荷载—位移曲线。通过对考虑粘结滑移和不考虑粘结滑移两种情况结果的对比,以及两种结果与试验结果的对比发现:计算结果可以较好地反映钢筋和混凝土之间的粘结破坏。
The RC structure under monotonic loading was analyzed including bond-slip effects based on fiber model,flexibility method.Consideration of bond-slip between concrete and bar,the corner and curvature of the components were calculated.During the course of iterative,the curvature were used to amendment the one of section.At last,the load-displacement curves were gained.By comparison between the results considered the slippage and ones not considered the slippage,as well as comparison between results of computation and results of tests:The results could reflect the bond damage between steel and concrete.
