Research on Effective Distribution Width in Crossbeam Calculation of Steel Box Girder Bridge with Overhanging Crossbeam
In order to solve the problem of calculating the effective distribution width of the crossbeam of the steel box girder bridge with overhanging beam,with the help of the study of stress distribution under the alignment load of infinite long plate strip,the effective distribution width diffusion angle corresponding to different bridge widths and different widths of overhanging beams is derived,and then the practicability and effectiveness of the derived effective distributed-width spread angle are verified in the actual project by using the plate shell finite element model and beam element model respectively.The results show that the calculation result of the beam element model with the derived effective distribution width spread angle is very close to the calculation result of plate shell finite element model,and can envelope the calculation result of plate shell finite element model,and he partial to safety.
