The structure of the deck was idealized in 3D under the 2000 SAP software and numerical simulation is done in MATLAB. Mobile source requesting apron is simulated by BC. Three types of structures girder bridge were considered the first with a range of 20 m, for the second we have increased the range 06 m (26 m) and similarly for the last range (32 m). One position of the moving charge we considered a .The apron centered loading was considered healthy in the first place; their responses under different speeds were compared for different lengths under the influence of mobile load. We introduced alterations in the structure which consists of the location of cracks in the middle of the bridge. The behavior of cracks according to the vibration can be considered as open or closed cracks. An analysis of the altered structure is formed under the same parameters. The healthy and altered structures were compared under different speeds effect and different lengths. It has been focused on the dynamic amplification factor (DAF) and the change depending on the scope of the bridge and the speed of the moving source.
