| Abstract: | In order to simulate the nonlinear hysteretic behavior of a RC structure refinedly,a practical simulation platform FENAP for a reinforced concrete(RC) fiber beam-column element is established,and the corresponding material library with multiple uniaxial constitutive models of steel and concrete is developed.In the platform FENAP,the damage effect of stiffness and strength degradation of members,the multi-dimensional coupling effect of axial forces and bending moments,and the binding effect of stirrups on co... |
