摘要
以江安第二过江通道钢混组合梁斜拉桥为例,分析了钢主梁的受力性能。介绍了该桥的工程背景,然后用有限元软件Midas建立整体模型,对钢主梁的受力进行分析,指导钢主梁设计。最后重点研究了钢混结合段的受力性能,采用理论计算方法对其进行受力分析,并采用有限元软件Ansys建立钢混结合段模型进行对比,验证了该斜拉桥钢混结合段设计的可靠性。
Presently,the steel cable-stayed bridge is widely used in large-span bridge.At times,the concrete were used to apply the weight on the sidespan of steel cable-stayed bridge,that was th steel-concrete composite girder.To receive the behavior of steel-concrete composite girder joint,a cable-stayed bridge with three towers located in Sichuan Province was used.The engineering background introduced.And the force behavior of the steel girder was analysed by finite element method.The the force behavior of steel-concrete composite girder joint were emphatically analysed with two different metheds,which were the calculating method and the finite element method.Then the results of the two metheds were compared and the reliability of the design with the steel-concrete composite girder joint was verified.
