TL;DR: In this article, the axial static mechanical behavior of circular carbon fiber reinforced polymer (CFRP)-steel composite tubed concrete stub columns was investigated, including an experimental study and a theoretical analysis.

TL;DR: In this article, the axial behavior of CFRP-steel composite tubed high strength concrete (HSC) columns has been investigated and the experimental results indicate that with enough CFRP sheets the load bearing capacity and deformation behavior of core concrete are significantly improved.

TL;DR: In this article, the authors investigated the behavior of CFRP-steel composite tubed reinforced concrete (C-STRC) columns under eccentric compression and observed failure modes, load-deformation curves, and load-stress curves of the steel tube and longitudinal reinforcing bars.

TL;DR: In this paper, the inherent difficulty of connections between thin-walled steel tubes and concrete-filled steel tube (CFST) columns has been discussed, and the benefits of using these tubes in CFST columns are discussed.

TL;DR: In this article, a fiber-based numerical model was developed to simulate the axial load versus lateral displacement curves, based on which the calculation method for the sectional load bearing capacity was developed through the section analysis.
