Evaluation of Shear Strain Distribution In Polypropylene Fiber Reinforced Cement Concrete Moderate Deep Beams

This paper describes a study on evaluation of shear strain and its variation as well as distribution across the width and depths in Polypropylene Fiber Reinforced Cement Concrete (PPFRC) moderate deep beams having span-to-depth ratio 2.0, 2.4, 3.0 and 4.0. Using micro mechanical measuring device a complete shear strain distribution-variation along with its response to the load deflection, crack patterns and modes of failures were studied experimentally. Twelve beams were tested and results of shear strain variation along vertical axis were plotted at various sections. Parabolic nature of shear stain distribution was observed along the vertical axis of plains situated at various depths.
