Identification of the Bearing Capacity of the Top-bearing Concrete-filled Steel Tube Truss Arch
The load test shows that the measured arch rib stress check coefficient is 0.79～0.96,the arch rib displacement check coefficient is 0.75～0.88,the bridge panel stress check coefficient is 0.75～0.83,the bridge floor deflection check coefficient is 0.87,and the resid-ual strain and deformation are<20%.Structural bearing capacity meets the design requirements.
