Abstract: This paper reviews the current development of the confined high-strength concrete (HSC). The differences between conventional concrete and HSC, the detailed mechanical characteristics of HSC, advantages and disadvantages, and the importance of confinement in HSC are critically reviewed. The beneficial effects of confinement in improving the low-ductility of HSC are also discussed. In addition, the recent progress in the research on confined HSC is presented. Subsequently, the existing stress-strain models for confined concrete are reviewed. In conclusion, the review paper notes and highlights some essentials points from the aforementioned discussion where several recommendations have been made for the advancement of this ever-developing topic.

Keywords: high-strength concrete; ductility; brittleness; confinement; steel straps.
