| Abstract: | The characteristics of the irregular box girder as well as its difference from the ordinary box girder on the special property of mechanics are analyzed in this paper.The space analytic methods,which chiefly include grillage method,solid element method and plate element method,are then introduced and employed.On the basis of a certain irregular box girder bridge and the corresponding space calculating theory,the mechanical characteristics of the irregular box girder on which the external loads and prestressed loads exert are obtained.The results are referential for the designers. |
