Abstract:
In view of the tensile stress of the studs caused by the transverse bridge lifting effect of the steel-concrete interface of the twin-I steel composite girder under the wheel load, in order to analyze the effect on the stress of the welding studs of the twin-I steel composite girder and provide a reference for the arrangement of the welding studs, the stud tensile stress distribution law and influencing factors of 2×35 m twin-I steel composite continuous girder were studied. The calculation results of transverse bridge lifting effect of steel-concrete interface of composite girder based on six kinds of ABAQUS finite element models with different element types, weld stud simulation methods and contact relations were analyzed. By comparing the test results in the existing literature, a reasonable finite element simulation method was determined. Based on the method, the influences of wheel load position, stiffener and crossbeam setting on the distribution of stud tensile stress along the longitudinal and transverse bridge directions were analyzed. The influences of girder position, the ratio of the thickness of bridge deck to the distance between main girders, and the transverse bridge distance between welding studs on the tensile stress of welding studs were studied, and the sensitivity of tensile stress of welding studs to various parameters was discussed. The results show that the stiffener limits the deformation of the upper flange of the steel girder along with the bridge deck, which leads to the obvious tensile stress of the welding stud. The stress of welding stud decreases rapidly along the longitudinal direction of bridge. The setting of crossbeam can reduce the lateral deformation of twin-I steel composite girder, which leads to a great increase of stud tensile stress, up to 317.97%. With the increase of the ratio between the thickness of bridge deck and the distance between main girders, the tensile stress of welding stud decreases gradually. With the increase of the distance between the center line of girder and the upper flange of steel girder, the tensile stress increases firstly and then does not change, and finally decreases slightly. With the increase of the transverse distance between welding studs, the tensile stress increases firstly and then decreases. Among the parameters, the ratio of deck thickness to girder spacing has the most significant effect on the value of stud tensile stress. According to the distribution of tensile stress and its influencing factors, it is suggested that the welding studs near the stiffener and girder of twin-I steel composite girder should be properly densified.
