behaviour of self-compacting reinforced concrete beams strengthened with hybrid fiber under static and cyclic loading

In this paper, total ten geometrically similar self-compacting concrete (ssc) specimens were tested, under static and cyclic loading. these consisting a set of one control scc and four strengthened ssc specimens of different percentages of fiber for static loading and similarly another set for cyclic loading. research work is aimed on developing hybrid fiber reinforced self-compacting concrete, and experiments were carried out to observe the optimum dosage and influence of hybrid fiber on self-compacting concrete beam specimens in static and cyclic loading. this study focused on load carrying capacity, energy dissipation, and the initial stiffness improvement of hybrid fiber reinforced self-compacting concrete beams with respect to control self-compacting concrete beam specimen under both static and cyclic loading. it can be concluded that incorporation of hybrid fiber with optimum dosage in concrete improved the ductility of concrete and failure was more ductile and gradual compared with control specimens.
