Analysis on Calculation of Crossbeam on Pier-Girder Consolidation of Curved Box Girder
Under the gravity and external load,the bend-twist effect of The box girder is obvious.In curved bridges the crossbeam plays an important role in strengthening the structure as a whole enhancing the horizontal connection among the main beams and improving the horizontal distribution of the load.So crossbeam must be paid more attention as primary member.In this paper,as the background of Xiamen BRT bridge,using the static models of different crossbeam systems,to research the crossbeam 0n pier-girder consolidation of curved box girder.And the re-sults show that force conditions of the two systems are close,but Reinforcement according to the calculation results of the beam model without considering the force of the top and bottom plates,the reinforcement is safe.
