Punching Shear Strength of High Strength Fibre Reinforced Concrete Slabs
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 11
Abstract
The experimental study of punching shear behavior of High Strength fiber reinforced concrete slabs is carried out in the present work. Each of 24 square slabs was simply supported along four edges and loaded to failure under a concentrated load over a square area at the center. The test parameters were the effective span to depth aid ratio, volume fraction of 3 types of steel fibers, slab thickness h, concrete strength fck, and size of load--bearing plate r. Test results indicate that the load-deflection curve of slabs exhibits four distinct regions that may be characterized by first cracking, steel yielding, and ultimate load. Within the scope of the test program, an increase in the values of pf, h, or r was found to lead to an increase in both the punching shear strength and the ductility of the slab. The ultimate punching shear strength of the slabs was compared with the predictions of equations available in the literature and code equations for reinforced concrete
