摘要:

根据已有试验,考虑初始荷载对结构影响,对表层内嵌FRP片材或筋材加固混凝土梁从加载至破坏全过程进行分析,得出加固构件的荷载挠度曲线,并与有关试验结果进行对比,计算结果与试验值吻合较好。

Abstract:

Based on experimental results of RC beams repaired by nearsurfacemounted (NSM) CFRP strips,nonlinear analysis of the whole loading behavior of strengthened beams is put forward.Calculation precedures of  deflectionload and momentcurvature are presented.Analysis values of the deflection agree well with test results for some tested beams in the reference.
