This work presents the results of an experimental campaign aimed at assessing the influence of cross-section geometry on the confinement of concrete samples. Four geometries were investigated: circular, square and two rectangular ones, characterized by different aspect ratios. Carbon fibers were used in the Fiber Reinforced Cementitious Matrix (FRCM) employed to realize the confining jackets. Samples were tested under uniaxial compressive stress, both adopting a cyclic and monotonic loading, to evaluate compressive strength, ductility and fibers strain exploitation ratio. Results indicate that the best performance is achieved by circular specimens, displaying the highest lateral pressure.

Abstract

This work presents the results of an experimental campaign aimed at assessing the influence of cross-section geometry on the confinement of concrete samples. Four geometries were investigated: circular, square and two rectangular ones, characterized by different aspect ratios. Carbon fibers were used in the Fiber Reinforced Cementitious Matrix (FRCM) employed to realize the confining jackets. Samples were tested under uniaxial compressive stress, both adopting a cyclic and monotonic loading, to evaluate compressive strength, ductility and fibers strain exploitation ratio. Results indicate that the best performance is achieved by circular specimens, displaying the highest lateral pressure.
