CFRP加固梁在承受弯曲荷载时的破坏是混凝土压碎、钢筋屈服、碳纤维未拉断。
CFRP Strengthening of concrete beams can fail when steel yield-concrete crushing and steel yield - CFRP tenside rupture.
两端加强角处钢筋首先达到屈服，形成塑性铰，荷载继续增大时，中间钢筋也达到屈服，此时沉箱隔墙已相当于一个可变体系，可认为结构已经破坏。
The steel bar of midspan also come to the yield strength when the load increased. At this time, the caisson has been destroyed, because the partition wall has already been a variable body system.
