Static Load Test of Concrete-filled Steel Tubular Arch Bridge

A concrete-filled steel tubular arch bridge has a span of 52m.To evaluate its working state and load carrying capacity,the bridge was tested under static loads after the bridge was constructed because of its poor appearance.Three container lorries with same carrying capacity were used.The test includes transverse load distributing coefficient of mid and quartile span of the main bridge,strain influence line of the main measuring point on critical section,strain and deflection of the main measuring point on critical section under basic load.The whole procedure of the bridge test was introduced briefly.The test data was sorted out and analyzed.
