Abstract:


The closed polynomial expressions for shear lag coefficient and effective width were given at the condition of Saint-Venant analytical solutions to full-span uniform load on flange slab of box girder. Availability of formula in this paper was demonstrated by comparing results with international norm and measured values.

Key words: thin-walled structure, effective width, shear lag coefficient, symplectic method
