Abstract:
In order to evaluate the applicability of the classical load lateral distribution calculation methods for simply supported steel plate composite girder bridges with small and medium span, firstly, a three-dimensional finite element simulation method based on ABAQUS was verified by the results of bridge load tests. Then, 108 analytical models were designed with different spans, number of main girders and spacing of main girders,and modified rigid transverse beam method, rigid-joint beam method, G-M method and finite element method were used to calculate the load lateral distribution influence lines, and then load lateral distribution coefficient of each main girder under single-lane and multi-lane were obtained respectively. Finally, based on the linear correlation coefficient, the degree of coincidence of the lateral distribution influence line and the relative error of the lateral distribution coefficient, the lateral distribution linear judgment and error analysis was carried out. The results show that when the aspect ratio of steel plate composite girder bridge B/L is less than 0.34, it is considered that the main girder deflects in a straight line under load, that is, the steel plate composite girder bridgewith B/L less than 0.34 can be considered as narrow bridge. When calculating the lateral distribution coefficients using the theoretical calculation method, for single-lane load, when B/L<0.2, it is appropriate to use modified rigid transverse beam method, rigid-joint beam method and G-M method. When 0.2<B/L<0.3, it is appropriate to use rigid-joint beam method and G-M method. When 0.3<B/L<0.75, it is appropriate to use G-M method. For multi-lane load, when B/L<0.3, it is appropriate to use modified rigid transverse beam method, rigid-joint beam method and G-M method. When 0.3<B/L<0.45, it is appropriate to use rigid-joint beam method and G-M method. When 0.45<B/L<0.75, it is appropriate to use G-M method. The criteria for determining the calculation accuracy of modified rigid transverse beam method, rigid-jointed beam method and G-M method are proposed, and the relative error of result between the theoretical calculation and the finite element calculation is controlled within 10%. The research results can provide a basis for the selection of load lateral distribution calculation methods for steel plate composite girder bridges with small and medium span.
