| Abstract: | Based on the potential energy theory,a set of equations indicating the potential energy of the normal indurated layered member under torsion is put forward;And with the veference to the minimun potential energy theory as well as the relationship between effective stress and strain,the elastoplastic torsion rigidity of the centrifuge concrete filled walled steel tube approaching to the limit state is analyzed.Therefore,an approximate solution convenient and feasible for the related practical application in engineers is providod. |
