针对水平荷载的横向分布问题,基于刚性横梁法计算弯梁桥的径向水平荷载的原理,研究了弯梁桥径向水平荷载的横向分布。以某桥为研究对象,利用非线性有限元软件建立了该桥空间弯梁模型,在验证了该方法可行性和准确性的基础上分析了径向水平荷载对主梁内力的影响。 In view of the horizontal distribution of horizontal load, the principle of calculating the horizontal load of the curved girder bridge based on the rigid beam method is studied. The horizontal distribution of radial load of the curved beam bridge is studied. Taking a bridge as the research object, the beam bending model of the bridge was established by using the nonlinear finite element software. The feasibility and accuracy of the method were verified and the influence of radial horizontal load on the internal force of the main beam was analyzed.
