DIFFERENT SIMULATION METHODS IN THIN-WALLED STEEL BOX GIRDER
Different simulation methods are introduced in the processing of modeling a large and complex thin-walled steel box girder. The main characteristics of this bridge are thin-walled, multi-cell, with large width-span ratio and orthotropic top/bottom/longitudinal-diaphragm plates. In order to analyze the actions of the bridge as a whole and reflect upon additional details such as deformation, stress distribution and shear leg etc., total comparisons are carried on using several different approaches. In addition, a similar scaled model is tested to verify the reliability of the computation model under load case. Based on the different analysis, a corresponding computational model is recommended. It is proved that it would be helpful to reduce the magnitude in the number of degrees of freedom employed to predict properties of this type of bridge more precisely.
