| Abstract: | The combinatorial element method of 3 D deteriorates beam and plate for static analysis of box girder under variable loads is introduced.And by the distribution graphs of normal stress and shear stress in the planes of box girder,some problems about the method of effective force in box girder under different transverse loads were discussed.Through actual calculations,the method proves to be simple and effective for box girder analys is. |
