TL;DR: In this article, the effect of axial load level on hysteretic behavior of CFTST columns was investigated experimentally, and the results indicated that the columns with axial loads below 0.5 exhibited plump hystertic loops with a slight pinching effect, better ductility and energy dissipation capacity.

TL;DR: In this article, the in-filled concrete strength of CFT columns is compared with the AISC-LRFD CFT column formulas and the test results reveal that the 1999 AISC LRFD design strengths are conservative and tend to penalize columns with higher concrete strength.
