钢桁式腹板组合截面在桥梁工程中的应用

Application of Steel Truss Web Composite Structure in Bridge Construction

钢桁式腹板组合截面能有效地减少结构自重,在大跨径梁桥应用其优点显著。本文介绍了该组合截面形式的主要特点,并与其他类型的钢-混凝土组合截面进行了比较,同时介绍了该截面类型在桥梁工程中的应用,并以法国的BrasdelaPlaine桥为例,重点介绍其在刚构桥中的应用。

With low weight of structure, steel truss web composite structures have obvious advantages in the constuction of long- span bridges. Properties of steel web concrete- steel composite structures are presented by comparing with other concrete - steel composite structures, and application of this type of structures in bridges especially for rigid - bridge is introduced in the paper in reference to the Bras de la Plaine bridge in France.
