Abstract
This article focuses on the experimental investigation carried out on controllability of structural performance of RC panels modified with optimal fiber hybridization system (hybrid combination of steel and polypropylene fibers) up to a volume fraction of 1.0%. Strength effectiveness of the mechanical properties, namely, compressive and splitting tensile strength as well as the structural performance of RC panels modified with optimal fiber hybridization system were studied. The results clarify that the optimal fiber hybridization system is seen to enhance the strength effectiveness of mechanical properties, the controllability-efficient of structural performance of RC panels as cracking behavior, and load—deflection curves, causing an increase in flexural ductility, toughness, and load-carrying capacity. Consequently, the hybrid combination of steel and polypropylene fibers can be used instead of individual fibers, in which innovation and responsible application of concrete construction technology results in better efficiency of the composite.
