Design of Steel Plate-Truss Composite Girder on Cable-stayed Minpu Bridge II, Shanghai

闵浦二桥是1座公轨两用一体化双层特大桥,主桥为独塔双索面双层斜拉桥。主要介绍主跨斜拉桥主梁设计的比选经过。最终采用钢板桁组合梁结构。该方案结构可靠、功能适用、构造简洁。

Minpu Bridge II is a super large bridge with the integrated double decks for both highway and light rail traffic. The main part is cable stayed through a single pylon and double cable sectors. Described hereby is how to select the main span girder from multiple options.
