摘要
本文用级数分析方法分析了钢筋混凝土箱梁开裂后的剪力滞效应,推得了剪滞应力公式.根据应力公式,本文还探讨了剪力滞效应随配筋率ρ等的变化情况.
In this paper, shear-lag effect in cracking reinforced concrete box girder is analysed by the method of harmonic analysis. Using the formula of shear lag stress, the coefficient of shear-lag for different percentage of reinforcement has been investigated and the results obtained are compared with reference [5].
