发布时间：2018-12-19 08:27
【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 solving method of superposition principle, a simple and convenient method for calculating shear lag effect of continuous box girder is presented, which is called fixed end method. The formula for calculating shear lag coefficient of continuous box girder under the action of dead load (uniform load) is deduced. The method is reliable and applicable to the calculation of shear lag of thin-walled continuous box girder by comparing with the results of limb method, superposition method and finite element analysis.
