Abstract: This paper presents the evaluation of creep coefficient on concrete-filled steel tubular (CFST) sustained loaded columns. A test of the long-term behaviour of CFST columns has been carried out. Shrinkage and creep of CFST columns are measured. A comparison of results calculated using three prediction models proposed by CEB-FIP, BAZANT-PANULA, and ACI have shown a good agreement with test results. The study also showed that the shrinkage effect of the concrete core in CFST columns is negligible. The creep coefficient measured and calculated by those recommanded CEB-FIP, BAZANT-PANULA, and ACI during 200 days were in agreement for CFST columns.The creep coefficient ultimate calculated for CFST columns has been found 2. At the beginning of test, the percentage of load taken by steel section was 38% and at the end of test, it was 56%. This is a stress transfer from the concrete section to the steel section due to the creep. This creep coefficient ultimate evaluated is proposed for long-term behaviour calculation of CFST columns. In order to take the effect of creep into account, applied sustained load must be multiplied by the value of (1+ ¤ćultimated)
