3 ) the average - strain of cross - section still can be assumed to be keep - in - plane within the whole loading procedure ; the theoretical moment - curvatures obtained by the cross - section keep - in - plane is consistent with the experimental ones . 4 ) the analytical flexural bearing capacity and cfrp - strain are more accurate by assuming the concrete ultimate strain to be 0 . 07 instead of 0 . 0033 ; 5 ) limiting the cfrp - strain under 0 . 01 is reasonable to evaluate the flexural bearing capacity of rc beams retrofitted with cfrp ; 6 ) the initial load is hardly influence the flexural bearing capacity of cfrp - strengthened rc beams 取混凝土的極限壓應(yīng)變0 . 007代替0 . 0033進行計算的結(jié)果能更準(zhǔn)確地評浙江大學(xué)碩士學(xué)位論文2004摘要價加固梁的抗彎承載力和cfrp應(yīng)變; 5 .在計算cfrp加固梁的抗彎承載力時,限制cfrp的應(yīng)變在0 . 01以內(nèi)的措施是恰當(dāng)?shù)? 6 .梁所承受的荷載的大小對加固后梁的抗彎承載力影響不大。
