| Abstract: | An analytical method is proposed for calculating free torsion constant of complicated thinwalled cross section from free torsion theory. A complicated thin-walled box girder is taken as a validity numerical example to verify the analytical method. Comparing with the finite dement results, this method has quite accuracy to simply calculate free torsion constant. |
