Numerical Simulation and Analysis of Seismic Response on Concrete-filled Steel Tubular Frame Model
Based on the model experiment on seismic responses of a single-span, 2-bays, 8 stories frame with circular Concrete Filled Steel Tubular (CFST) columns and H-shape steel beams on the shaking table, the influence of the nonlinearity of materials and geometry were considered, and a command stream is edited with the ANSYS Parametric Design Language (APDL), and the nonlinear finite element analysis on the seismic responses of the model frame was completed. The calculated results are much coincided with the tested results. The influence of the axial compression ratio and the confining coefficient on seismic response of the frame structure was analyzed by the finite element model above, and the results showed that the raise of axial compression ration and confining coefficient could respectively result in the increase and decrease of the story drift angle of CFST frame.
