| Abstract: |
| By using present constitutive models of high strength concrete and steel tube filled with high strength concrete, a calculational procedure is authorised for nonlinear analysis of moment curvature relation of laminated column with high strength concrete filled steel tube. Then, The influence of some parameters on the relationship are studied. Finally, a trilinear model of the relationship is presented and the statistical formula of characteristic parameters of the model are established. |
