Concrete-filled steel tubular (CFST) columns are adopted in many structural applications, especially for tall buildings, bridges and large infrastructure due to their substantial structural and economic benefits. However, the design guidelines for CFST columns with high strength materials and slender sections are still limited. In acknowledging these limitations, a large number of tests on high strength CFST columns have been conducted. In this paper, the most recent experimental data on CFST columns with high strength materials and slender sections are collected and merged with existing databases to establish a comprehensive database with over 3100 tests. The test results are then compared with those predicted from existing design codes, including Eurocode 4, Australian/New Zealand code AS/NZS 2327 and American code AISC 360-16 to calibrate their accuracy in strength prediction of CFST columns. In general, all codes give conservative predictions for CFST columns. Eurocode 4 and AS/NZS 2327 give the best predictions, whilst AISC 360-16 gives conservative predictions. The effects of material strengths and section slenderness on the code predictions are also investigated to evaluate the applicability of the codes beyond their material strength and section slenderness limits.
