    Abstract
  • In order to reveal the mechanism involved in base-metal cracking of floorbeam cutout on orthotropic steel bridge deck, the finite element program ANSYS was employed to establish both the segmental model of steel box girder and the local submodel of bridge deck, and the check of mesh independent was conducted to ensure the calculating precision.Thereby, the stress response characteristics of floorbeam cutout were analyzed under moving wheel loads, the fatigue evaluations were performed based on hot spot stress method and nominal stress method, respectively, and the influences of floorbeam thickness and cutout shape on the stress of structural detail stress were discussed.Research result shows that the length of stress influence line of floorbeam cutout detail in longitudinal direction of bridge is 2 times of floorbeam spacing, thus, loading with merely middle-axle group is appropriate.According to AASHTO LRFD, a fatigue truck with five axles can generate 2 or 3 stress cycles at the structural detail.The worstlongitudinal and transverse loading locations of floorbeam cutout are the wheel loads center locating at the intersection of rib wall and deck plate, and the front wheel of middle-axle group locating at 0.3 mfrom the floorbeam, respectively.The angle between the stress direction of stress concentration point of floorbeam cutout edge and the horizontal plane is 67.2°.Fatigue assessment result is closely relevant to the nominal stress extraction position.The hot spot stress method based on fatigue life curve of FAT125 is feasible for the fatigue assessment of floorbeam cutout.According to the equivalent principle of fatigue damage, the stress at 5 mm from cutout edge can also be extracted for the fatigue assessment base on the nominal stress method.It is suggested that the cutout shape in Eurocode 3 (highway bridge) with a large curve radius is preferable, and the hot spot stress reduces by 12.4% compared with the researched cutout shape.The stress range is below the cut-off limit as the thickness of floorbeam is not less than 12 mm, hence the cutout reaches a infinite fatigue life.Floorbeam cutout cracking is related to poor cutout shape, thin floorbeam, imperfect fabrication technology and high truck traffic volume.
