Structural Design and Study of 245 m Long Span Composite Steel Box Girder Bridge
With the main span length of 245m,the approach bridge across embankment on the north side of the Yellow River Bridge on Fenghuang Road in Jinan is a combined steel box girder structure,ranking the first of its kind in China up to date.The design of bridge panel and double-layer composite structure in the negative bending moment area of continuous beam is analyzed and studied in the paper,which reflects the concept of combining design and construction.The research improves the technical and economic competitiveness of long-span continuous composite box girder.
