摘要
采用余能定理从理论上推导出适合于侧贴预应力碳纤维布加固连续梁的挠度计算公式,并通过实验得到未加固、侧贴普通碳纤维布加固、侧贴预应力碳纤维布加固连续梁的荷载—挠度曲线,与理论计算结果作对比,验证了侧贴预应力碳纤维布加固连续梁挠度计算公式的合理性。
The paper adopts the complementary energy principle to deduce the deflection calculation formula suitable for the side-bonded pres- tressed carbon fiber cloth continuous reinforced concrete beam and achieves the loading-deflection curve of the unreinforced, the consolidation with the side-bonded common carbon fiber cloth, and the side-bonded prestressed carbon fiber cloth continuous reinforced concrete beam, com- pares its results with the one by the theoretic calculation, and proves the deflection calculation formula for the side-bonded prestressed carbon fi- ber cloth continuous reinforced concrete beam is reasonable.
