Bending Behaviour of Concrete Beams with Composite Reinforcement

Abstract

Massive quantities of finite resources have been depleted due to the construction and building sectors. Using bio-products to reduce raw materials use is seen as a major step toward a sustainable building sector. In this regard, the current research developed a novel composite beam reinforced and double-confined using a flexural and shears continuous FRP-Jacket. The suggested method involves swapping out conventional Portland cement-based concrete with a greener variant made with a different mix percentage that includes dry clay and hydraulic lime. Experimental testing and theoretical modeling based on shear stress and deformation composite beams are used to assess the bends & shear performance of the suggested design with four-point flexural load. The double-confinement approach used resulted in a noticeable improvement in strength and deformability compared to conventional concrete beams, as shown by strong agreement between experimental and modeling results in terms of effective stress, pressure concentration, and cement reduction.
