英文摘要	The hysteresis relationship in concrete-filled steel tubular (CFST) frames during seismic loads was analyzed for composite frames having CFST columns and H-shape steel beams. The model was based on fiber nonlinear beam-column element theory and the OpenSees Software, nonlinear material and geometric conditions to simulate the hysteresis to the reverse lateral loading versus the lateral displacement. The stress-strain relationship of the confined core concrete was considered, with a bilinear stress-strain model with strain hardening for the steel. The numerical results agree well with experimental results with steel yield strength of 235-420 MPa and concrete cube compression strength of 30-90 MPa.
