| Abstract: | Through an example of assembly type hollow plate girder bridge,this paper uses the finite element software ANSYS with the influence of temperature field and different vehicle driving,discusses the effect of the hollow plate girder bridge＇s temperature stress on hinged joints disease in different conditions,analyzes the complex force state of the longitudinal hinge joints and its failure mechanism in different vehicle load conditions,puts forward the design method and structural measures,which can prevent the cracks of the plate girder bridges and failure because of the hinge joints. |
