| 摘 要： | 以能量变分原理为基础,在曲线箱梁侧向综合考虑了剪力滞后和剪切变形效应的影响,建立了薄壁曲线箱梁的侧向弹性控制微分方程和自然边界条件,获得了相应广义位移的闭合解.论文提出了一种曲线箱梁侧向静力学特性分析的解析法,揭示了各参数之间的内在联系.算例中论文解析解与板壳有限元结果吻合较好,证明了本文方法的有效性,因而更具理论价值...

| Abstract: | Based on the energy variation principle,this paper proposes an approach of analyzing the effect of shear lag,shear deformation on the lateral static characteristic of curved thin-walled box girders generally applied in engineering.The minimum potential principle is applied to establish the lateral governing differential equations and the corresponding natural boundary conditions.The closed-form solutions of generalized displacements are obtained.The variations of shear lag effects of curved box girders,caus... |
