摘要
Abstract
To analyze the anti-overturning stability of long-span curved girder bridges under traffic loads,the self-devel-oped vehicle-bridge coupling vibration analysis program was unutilized to establish a three-dimensional finite element bridge model and a 17-degree-of-freedom vehicle dynamic model.The vehicle-bridge coupling vi-bration equation was derived based on the finite element method and d'Alembert's principle.A numerical sim-ulation FORTRAN program was developed based on the modal superposition method and Newmark-β numeri-cal integration method to investigate the response characteristics of vehicle speed,vehicle driving eccentrici-ty,bridge support spacing and other factors on the bridge support reaction.The influence of these factors on the bridge anti-overturning stability was analyzed.关键词
