摘要
近年来,随着钢混组合结构桥梁设计理论与工程实践的发展,钢混组合结构桥梁在我国桥梁工程领域中得到了越来越多的关注。双主梁组合钢板梁桥具有结构受力明确、造型美观、钢材指标低、施工快等综合优势,逐渐在桥梁建设中得到广泛应用。以实际桥梁工程项目为背景,结合相关规范,通过有限元计算分析,对双主梁组合钢板连续梁桥纵向主梁和大横梁进行了设计与计算,提出了双主梁组合梁桥的纵向主梁和横向大横梁的设计与计算要点,可为组合钢板梁桥的设计计算提供参考。
In recent years,with the development of design theory and engineering practice of steel-concrete composite bridge,the steel-concrete composite structure bridge has received more and more attention in the field of bridge engineering in our country. The double-main-girder steel plate composite girder bridge has comprehensive advantages such as clear structure force,beautiful shape,low steel index and fast construction,and it has been widely used in bridge construction. In this paper,based on the actual bridge engineering project,combined with relevant specifications,through finite element calculation and analysis,the design and calculation of the longitudinal main girder and the large cross girder of the double-girder composite steel plate continuous girder bridge are carried out,and the design and calculation points of the longitudinal main girder and the transverse large cross girder of the double-girder composite girder bridge are put forward,which can be used as a reference for the design and calculation of the composite steel plate girder bridge.
