摘 要: 利用最小势能原理建立了考虑多因素的分析薄壁曲线箱梁剪滞效应的控制微分方程及其边界条件,为考虑多因素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-factor of thin walled curved 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 muhi-factor.
