Research on Key Problems of Through Steel Arch Bridge with Wide&Long Span Composite Beam
Composite beam steel arch bridge has been widely used because of its reasonable stress,economic cost,beautiful appearance and other characteristics.According to the design practice of a wide and long-span composite beam steel arch bridge,the structure of arch rib,end beam and suspender was optimized,forming a unique four cable plane bifurcation arch method,taking into account the structural appearance,mechanical properties and engineering economy.Through theoretical analysis and load test detection,the safety of this kind of design optimization is verified,which can provide reference for the design of the same type of bridge.
