BEHAVIOUR OF HIGH-STRENGTH CONCRETE UNDER CONFINED STRESSES

Abstract This paper presents the preliminary results of an experimental investigation on confined high-strength concrete, which is ongoing in the Civil Engineering Department of the Universite de Sherbrooke. The results of the present preliminary study limited to concentrically loaded short circular columns show that: 1. confining high-strength concrete in a steel tube greatly increases its strength and results in outstanding new ultrahigh-strength concrete; 2. - confining high-strength concrete in a steel tube improves its ductility; 3. - the confinement efficiency slightly increases with concrete compressive strength.
