Analog static elasto-plastic analysis for shaped column frame experiment

In this paper, the 1/3 ratio model of reinforced concrete deformed column for low-cycle repeated load experiment is adopted, the common finite element software SAP2000 is used for analyzing the model's performance of bearing capacity, ductility, Occurrence order of plastic hinge, the yield mechanism and inter-layer displacement. The results show that the selected madel can simulate the nonlinear performance of the shaped column frame accurate, the calculated value is in good agreement with the experimental values.
