In this study, in order to investigate load-carrying behavior of the reinforced concrete filled steel tube, three-point bending test and 3D elasto-plastic analysis were conducted. An applicability of the proposed numerical analysis method was investigated comparing with the experimental results. The results obtained from this study were as follows: 1) it was observed that the surcharged load was gradually increased until filled concrete was cracked and popped out from the end of tube; 2) since the surcharged load after the concrete being cracked was distributed around 620 kN which is 90 % of maximum load, the high ductility of RCFT was confirmed; and 3) the load-carrying behavior and strain distribution of the RCFT may be better simulated by means of the proposed analysis method. |
