Tests to estimate the cooperation between confined concrete and column reinforcement up to compressive failure

Rapport, 2005

The stability and strength of reinforced concrete columns confined by tangential external CFRP wrapping is studied. The plain and confined columns of slenderness λ = 66.7 and λ = 16 with or without longitudinal steel bar (with diameter 12 mm and 16 mm) reinforcement are tested. Two batches of concrete with different ultimate compressive strength are investigated.
