Design of 85 m Steel-Concrete Composite Beam for Main Bridge of Qisha Hub Interchange
The use of steel concrete composite structures for bridges of the Shiziyang Link Project is actively promoted.For conventional span bridges with a length of 50≤L≤60 m,standardized steel concrete composite structures are used.For larger span bridges with a length of 60 m＜L≤85 m,specially designed steel concrete composite structures are also widely used.In the paper,the design of the 85m steel-concrete composite bridge of the main bridge of the Qisha Hub Interchange is taken as an example to introduce the advantages and disadvantages of the steel-concrete composite bridge type and its adaptability to large spans.The typical section layout,design principles,and structural details of large-span steel concrete composite bridges are analyzed.The advantages and disadvantages of different construction methods for steel concrete composite bridges as well as their impact on structural stress are compared.
