摘要
应用大型通用有限元软件建立多个跨径不同桥面板厚度的刚架拱桥模型,对比优化前后的跨中荷载横向分布系数、控制内力和挠度值表明,增设一片刚架拱片优化了上部结构的整体受力,显著提高了刚架拱桥的整体刚度和承载能力。
Abstract：Using the large-scale finite element software to create the rigid frame arch bridge model with multiple spans and multiple bridge decks, the comparison of the transverse load distribution coefficient in midspan, control internal force and deflection before and after optimization shows that adding a piece of rigid-frame arch can optimize the global stress of superstructure and increase the overall stiffness and load capacity of the rigid frame arch bridge significantly.
