Static Load Test of a Through Concrete-Filled Steel Tubular Arch Bridge

A through concrete-filled steel tubular arch bridge which has a span of 80 m has been tested under static loads.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 underbasic load.The results show that the strain checkout coefficient and deflection of each measuring point are lower than the criterion value,which indicates that the positive section strength and structure strength can meet the normal requirement.
