Comparative Study of Hybrid Fiber Reinforced Concrete Deep Beam under Shear IJTSRD
As per the Indian standard a beam shall be considered as deep beam when the ratio of effective span to overall depth is less than 2 for simply supported & 2.5 for continuous beam. Deep beam transfer the load by shearing action rather than flexural action. Shear strength of concrete beam is not well defined as it is complex phenomenon. To improve shear strength & deformation of cement matrix mixed (Crimped steel – Polypropylene) fibers are used. By adding steel fiber it is observed that crack resistance and crack control is improved. Also polypropylene fiber is improving compressive strength, shear strength, resistance to aggressive agents, micro crack control. Therefore we use hybrid fibers (Crimped steel – Polypropylene) as reinforcement in concrete to improve homogeneous, isotropic characteristics, Tensile & shear response by arresting micro crack, crack penetration & propagation. The several recently published articles & technical papers dealing with implementation of hybrid fibers in concrete matrixes.
