Static and Dynamic Test Detection of Steel Tube Truss Arch Bridge

Abstract:

Static and dynamic test of 85m span half-through steel tube concrete truss arch were in. Follow contents were determined in the static test:control section deflection of steel tube concrete arch rib under test load;deck control section deflection and strain measuring in test load;deflection and strain measuring of suspender beam;strain test of suspender;crack observation of beam in loading. The deflection and strain measuring point of deck control section were on the beam. The content of dynamic load test :the measuring of impact coefficient、natural frequency and cable tension by frequency methods. Finally, operational situation of bridge was estimated.
