悬吊单肋拱桥空间分析与设计

Spatial Analysis and Design of Suspended Single-rib Arch Bridge

悬吊单肋拱桥为体现悬吊的空间美感,吊杆与主梁连接方式具有空间层次感,同时具有梁体高度低、造型美观、结构新颖的优点,多用于市政景观桥梁设计。文章结合工程实例,采用有限元分析桥梁模型,并经结构计算比较后,该种桥梁结构形式能充分发挥钢结构与混凝土的材料受力特点,在强度、稳定等指标上均满足规范要求。

The suspension single rib arch bridge reflects the spatial beauty of suspension,and the connection between the suspension rod and the main beam has a sense of spatial hierarchy,At the same time,it has the advantages of low beam height,beautiful appearance,and novel structure,and is often used in municipal landscape bridge design.Combining with engineering examples,finite element analysis was used to analyze the bridge model,and after structural calculation and comparison,it was found that this type of bridge structure can fully utilize the material stress characteristics of steel structure and concrete,and meet the requirements of specifications in terms of strength,stability,and other indicators.
