The failure pattern of prestressed AFRP sheets is fracture, but that of non-prestressed AFRP sheets is debonding. 承載力極限狀態(tài)時(shí),預應力梁為纖維布的斷裂破壞,非預應力梁發(fā)生布與混凝土間局部脫粘破壞。
According to the results of the experiment and the nonlinear finite element analysis, we improve the form of the slabs strengthened by sheets and get a good effect. 根據試驗以及有限元分析的結果,對采用纖維布加固方形板的形式進(jìn)行了改進(jìn),并取得了較好的效果。
