| Abstract: | In recent years,with the rapid development of steel-concrete composite girders in China,small and medium-span steel composite bridges have been widely used.In this paper,a three-dimensional model of the 30~40m composite girder with four main girders was established by FEM method to study the influence of the parameters of the transverse connection system,such as number,size and vertical position on the stability performance.The result showed that when the overall instability of the steel girder occurred,increasing the number and size of the transverse connection system or arranging it close to the compression flange could improve the stability performance of the main girder;while when the local stability of the compression flange occurred,changing the design parameters of the transverse connection system had little impact on the stability performance of the main girder. |
