Abstract: 
This paper presents an experimental study of the impact factors of mobile cranes on short span bridges. Previous studies have looked at the impact factors for abnormal vehicles in general but there has been no focus on mobile cranes which have different suspension system and axle configurations. Field tests were performed on a medium span concrete to measure the dynamic impact caused by a 36 tons mobile crane. A wooden plank was placed across the instrumented beam to model a deteriorated road surface. Field measurements were used to calibrate a finite element model representing the vehiclebridge interaction. The study has found that the impact caused by the mobile crane is dependent on its speed, suspension system, weight and condition of road surface.
