Cover Story: A novel concrete-filled corrugated steel tube (CFCST), consisting of corner steel bars and corrugated steel plates filled with concrete, was proposed. This study presented a numerical analysis to evaluate CFCSTs’ stability performance under eccentric compression, a common condition for columns with large height-to-width ratios. The results showed that the N-M interaction curve became less convex as the height-to-width ratio increased. Concrete strength and column width had a significant impact on the stability performance at low eccentricity ratios, while steel strength and bar width became more influential at higher eccentricities. A comparison with AISC 360 and GB 50936 revealed their limitations in predicting CFCSTs’ stability performance. A new formula was ultimately proposed with an error of less than 15%. View this paper
