unloaded antenna-
At first, the experiment carried out by tianjin university has been analysed according to the " nonlinear balance trying calculation " method, and the values of yield load and ultimate load agree with the test result better, and the curve of bending moment - curvature, bending moment - deflection can agree with the results. the second, the simplified formula for evaluation the ultimate flexural capacity of cfrp strengthened rc members is presented according to the three probable failure modes ( compression failure ; cfrp rupture ; crushing of the concrete in compression before yielding of the reinforcing steel ). it is applicable to both singly and doubly reinforced rectangular sections, as well as flanged sections
首先利用鋼筋混凝土非線性平衡試演算法對天津大學試驗進行了理論分析，所得分析值與試驗結果相比，加固梁的屈服荷載、極限荷載能夠很好地吻合，彎矩曲率關系曲線及彎矩撓度關系曲線較為吻合；其次，為了滿足實際工程的需要，根據碳纖維布加固構件可能發生的三種破壞形態（壓區混凝土壓碎破壞、碳纖維布拉斷破壞以及受拉鋼筋尚未屈服時壓區混凝土已壓碎破壞） ，區別三種鋼筋混凝土構件截面形式（單筋矩形截面、雙筋矩形截面、 t形截面） ，分別給出了碳纖維布加固混凝土構件抗彎承載力的簡化計算公式和適用條件，並進一步探討了這三種截面形式下進行加固設計和復核的步驟。
