For a better understanding of the strains and stresses,numerical simulation was conducted by using ANSYS under the assumption of absolute bond between the steel and concrete.The results show that the stresses and strains in such concrete and steel rings are uneven;the curves of strains and stresses change gradually around the interface.To ease numerical computation,the mechanical system was simplified under the assumptions of synchronous deformation and uniform strains and stresses.The results of the numerical simulation and simplified stress calculation can match almost perfectly.It means that the simplified mechanical model can be used in stress and visco-elastic behavior quantification.
