文章提出了分析空间梁拱组合式桥梁荷载横向分布的弹性支承连续粱法,实例计算及试验结果表明;用该法计算的荷载横向分布系数与实测挠度值反算的荷载横向分布系数基本吻合,对城市道路以三块板布置的间梁拱组合式桥梁结构,一般以靠近机动车道内侧梁拱拱片的横向分布系数较大,并控制设计。
In this paper, a continuous beam method for analyzing the transverse load distribution of beam-arch bridge is presented. The calculation results and experimental results show that the transverse load distribution coefficient calculated by this method is in good agreement with the inverse load deflection factor. In the case of the composite beam-arch bridge structure with three plates laid on the urban road, the lateral distribution coefficient of the beam arch near the inside of the motor vehicle lane is generally larger and the design is controlled.
