Torsion Analysis of Horizontal Curved Box Girder under Temperature Difference

  • In order to calculate the internal forces and displacements of horizontal curved box girders under temperature difference correctly,the torsion deformations caused by section rotation and temperature difference were analyzed based on the characteristic of the flexure-torsion coupling,and the torsion and deflection of simply-supported horizontal curved box girders were calculated.By taking a simply-supported horizontal curved box girder as an example of simple structures,a method to calculate internal forces in continuous box girders was put forward.The internal forces in a continuous curved box girder with two equal spans were calculated with this method and compared with the results of 3-D finite element analysis to show an error of less than 5%.The research shows that when the displacement and internal force of horizontal curved box girders are calculated,the torsion deformation caused by temperature difference should be taken in account.
