摘 要: 利用最小势能原理建立了考虑多参数及剪切变形的分析薄壁箱梁剪滞效应的控制微分方程及其边界条件 ,为考虑多参数薄壁箱梁剪滞效应建立了理论分析基础 . The governing differential equations and boundary conditions considering multi-parameters and shear deformation of thin walled box girders are established by minimum potential energy principle to analyze the shear lag effect, which set the foundation of theoretical analysis of shear lag effect in thin walled box girders by multi-parameter.
