【摘要】 平面曲线桥,由于弯扭耦合作用,横梁对于增强桥梁的结构整体性,加强主梁之间的横向联系,改善荷载横向分配等起到重要作用,因此应把横梁作为主要受力构件加以考虑。本文对计算方法进行了分析和探讨,认为用梁格法进行有限元建模值得推荐,并通过算例进行分析,提供一些参考。更多还原

【Abstract】 In curved bridges, the crossbeam plays an important role in strengthening the structure as a whole, enhancing the horizontal connection among the main beams, and improving the horizontal distribution of the load. So crossbeam must be paid more attention as primary member. In this paper, through the analysis and discussion of calculation theory of crossbeam, calculation based on beam-gird theory by using spatial 3-D Finite Element Method should be applied, and a numerical example is calculated for reference.更多还原
