【摘要】 应用在集中荷载和均匀变温作用下一次超静定曲线梁的跨中位移公式,对实际曲线桥进行分析求解,得出在均匀变温和各支撑柱顶部摩擦力共同作用下实际曲线桥跨中横向位移.并根据实际曲线桥结构建立有限元模型,将有限元解与应用结构力学方法求出的解析解进行比较,结果表明了这种计算方法的有效性和可行性.更多还原

【Abstract】 Multispan curved bridge is analyzed based on hyperstatic curved beam transverse displacement formulae under concentrated load and uniform temperature loads.Multispan curved bridge transverse displacement formulae under the effect of support frication and uniform temperature loads are presented.By comparing analytic value of structural mechanics method and finite element value of multi-span curved bridge model,the validity and feasibility of the calculating method have been proved.更多还原
