New technique for reinforcement of concrete columns confined by embedded composite grid

摘要

Reinforced concrete structures are often very sensitive to accidental loads, leading to deterioration, failures and human life fatalities. Our concern is to reinforce the concrete columns by composite materials judiciously integrated in order to ensure, on one hand, a return of sufficient rigidity and strength preventing overall collapse and, on the other hand, to preserve external and esthetic aspect of reinforced concrete works. The experimental and numerical studies in the present work represent a promising revelation regarding the effectiveness of the proposed confinement process by integrating a composite grid with rectangular mesh containing glass fibers inside the reinforced concrete matrix.
