| Abstract: | A three-dimensional real modelling of bolting-welding connection and full-welding connection of beam-column in concrete-filled rectangular and square steel tube (CFRST) frames is conducted using the finite element software ANSYS,based on which the hysteretic behavior of the two connections under low-cycle repeated load is studied using the nonlinear finite element method,whose aseismic performance is also compared. The results show that the aseismic performance of the full-welding connection is superior to that of the bolting-welding connection. |
