Effect of Strengthening Axially Loaded Circular Self-Consolidating Short Columns with Expanded Metal Mesh

Abstract

Superior confinement for concrete column cannot be provided by traditional lateral ties reinforcement due convergence of bends and twists caused due to lateral reinforcement. In this paper, the enhancement in confining the steel bars due to the utilization of metal mesh any case to the regular tie reinforcement is studied. Totally 5 column specimens were cast and cured. A control specimen was prepared and remaining 4 specimens were internally wrapped using Expanded Metal Mesh (EMM). Mesh Apertures are differed having constant mesh thickness. Self-Consolidating Concrete was adopted in place of congested reinforcement. The specimens were tested under uniaxial compression in universal testing machine until failure. The results show that the strength and ductility has been improved for internally confined concrete column specimens.
