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。
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.
