• Cyclic behavior of concrete columns wrapped with Fiber Reinforced Cementitious Matrix.
• Experimental tests on monotonic and cyclic axial compression.
• Investigation on effect of confinement level, cross-section shape and corner radius.
• Gain in compressive strength, deformability and absorption energy capacity.
The main results of an experimental research aiming to investigate the behavior of medium-size low-strength concrete columns wrapped with Carbon Fiber Reinforced Cementitious Matrix (CFRCM) under monotonic and cyclic compressive axial loads are presented. Thirty columns with circular, square and rectangular cross-sections were tested under monotonic and cyclic axial loads to investigate the effect of the confinement level, the cross-section shape and the corner radius on the stiffness, strength, and ductility of CFRCM confined concrete columns under cyclic loads. The results prove that CFRCM confining jackets provide substantial gain in compressive strength, deformability and absorbed energy.
