摘要
为了解斜拉索索力在主梁中的传递规律及主梁的剪力滞效应情况,以清远市某大桥主桥为研究背景,通过建立有限元模型,研究单索面宽幅斜拉桥主梁在成桥阶段的受力特性及剪力滞效应,分析结果显示,该桥主梁有合理的受力且剪力滞效应处于可接受范围。
In order to understand the transmission law of cable force in the main girder and the shear lag effect of the main girder,taking a bridge in Qingyuan City as the research background,this paper studies the mechanical characteristics and shear lag effect of a wide cable-stayed bridge with single cable plane in the bridge forming stage by establishing a finite element model.The analysis results show that the stress of the main girder is rea-sonable and the shear lag effect is acceptable.
