Five prestressed concrete testing beams were designed with different reinforcing distance. based on experiments of frp prestressed concrete beams, failure pattern 、 load - deflectioncurve 、 stress increasing and so on are studied systematically
設計了五根不同加固距離的試驗梁，對試驗梁的受力過程、破壞形態、荷載-撓度曲線、纖維筋應力增量等進行了詳細分析。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。Through the experimental and theoretical analyzing results, the conclusion can be summarized as follows. 1 ) the yielding load and ultimate bearing capacity of the beam are not affected by the value of the load under that load the cfrp sheets were retrofitted, but the value will affect the stiffness of the beam, especially the average tangent stiffness after rebar yielding. 2 ) the stiffness of cracked beams retrofitted with cfrp sheets is larger than that of the normal rc beams
通過試驗結果分析發現，採用cfrp加固的鋼筋混凝土梁的剛度較普通鋼筋混凝土梁的剛度有明顯提高，纖維布對承受以抗彎為主的構件具有增強剛度、控制撓度的作用；纖維加固時梁所承受的荷載大小，即加固時梁內已存在的彎曲裂縫的寬度對梁的屈服荷載及極限承載力影響不是很大，但對梁的剛度有較大影響，特別是對縱筋屈服后的剛度影響較大。
