Abstract

In order to simulate the behavior of column in which local buckling occurs, we made the numerical program which considers axial force and biaxial bending moments. The program is able to analyze strain hardening and strength deterioration with generalized plastic hinge. Additionally, in order to analyze the local buckling behavior, we set the multiple yield surfaces, the lower limit value of the moment, and reduction of unloading stiffness. By using this program, we were able to trace static and dynamic loading experiments under axial force and biaxial bending.
