Design and Mechanical Performance Analysis of Curved Steel Box Girder Bridge with Long Span Hidden Beam
Urban interchange wiring is generally more complex due to land restrictions,bridges are often located in curved sections,and pier space is limited.Curved steel box girders with hidden beams are widely used in urban overpasses because of their strong crossing ability,small building height and flexible pier layout.However,the structure of such bridges is complicated and the spatial effect of structural force is obvious.In order to further study the mechanical performance of this kind of bridge structure,an actual four-span curved continuous steel box girder bridge was taken as an example,based on the orthotropic plate theory,and the midas finite element analysis software was used to establish the calculation and analysis model of the first system of main beam,the second system of main beam and the beam.Through the structural calculation of the main beam,the rationality of the overall design of the bridge is verified,and the key points of the design of the bridge are pointed out.
