大跨度钢桁架拱桥拱梁结合关键节点设计

Design of Key Joints of Arch - Girder Junction of Long-span Steel Truss Arch Bridge

摘要:

以某主跨48 m+180 m +48 m钢桁架拱桥为背景，介绍了中墩、边墩处拱梁结合部关键节点的设计关键技术和思路，并建立梁、壳结合的混合有限元分析模型，验证节点设计的合理性。

Abstract:

Based on a steel truss arch bridge with a 48 m+180 m+48 m main span, the key design technique and thinking of the key joints of arch - girder junction at the middle pier and side pier are introduced. A finite element analysis model of girder - shell junction is built to verify the rationality of joint design.
