摘要
双工字主梁的间距与横梁的数量是双工字组合梁桥设计的关键因素,文中采用用有限元软件ANSYS建立相应的分析模型,研究这两项因素对结构性能的影响。结果表明横梁主要作用是提高荷载在主梁间的传递效率;主梁间距对桥面板挠度影响显著,建议主梁间距取值为6~8m。
The distance between the main girders and the number of cross-beams are the key factors in the design of twin I-girder composite bridge.In this paper,to study the effect of these two factors on the structural performance,the corresponding analysis model is established by using the finite element software ANSYS.The results show that the main function of the cross-beam is to improve the load transfer efficiency between the main girders.Moreover,the main girder spacing has a significant impact on the deflection of the bridge deck,and the main girder spacing is recommended for 6~8m.
