摘要: 在叠加原理求解法基础上,提出简便且满足精度要求的连续箱梁剪力滞效应实用计算法—固定端法,推导出连续箱梁在恒载(均布荷载)作用下的剪力滞系数计算公式。通过与解肢法、叠加法以及有限元分析结果的比较,本方法可靠,适用性强,适用于薄壁连续箱梁剪力滞的计算。

Abstract: Based on the superposition principle, a simple and practical calculation method to solve continuous box beam shear lag effect, that is, the fixed end method was proposed, which also met the accuracy requirements. The calculation formula of the shear lag coefficients of continuous box girder in constant load (even load) was derived. Through comparing with the results obtained from dissecting method, superposition method and finite element method, the proposed method turned out to be reliable and applicable, which was suitable for the calculation of the shear lag of thin walled box continuous beam.

Key words: bridge engineering, continuous box girder, the shear lag effect, fixed end method, boundary condition
