Experimental Investigation on Torsional Behaviour of Coconut/Steel Fiber Using Reinforced Concrete Beam

Abstract

This study examines and investigates the outcomes for coconut fiber/steel fiber concrete beams As compared to traditional concrete beams, which are applied to torsion. Four beams, two of them with coconut fiber/steel fiber concrete and another two of them with traditional concrete with manufactured sand were developed and tested. The research contains specific cracking features, pre-cracking performance including analysis, post cracking performance and evaluation, limited torsional reinforcing, torsional reinforcing, ductility, crack width and stiffness. These were noted that coconut shell concrete's torsional activity is compared with that of traditional concrete. Compared with ACI projection, Macgregor’s proposed method is more cautious in measuring torsional resistance to deformation. And for calculating the ultimate torque force ACI projection are more moderate Contrasted to the Macgregor proposed formula. In this respect, Indian standard is also progressive, but it has been undervalued in comparison with ACI and the Macgregor constants. Reasonable torsional reinforcement for beams is required to ensure the beam does not failure to crack. The influence of 5, 10, 15, 20% fiber contents by mass of cement and fibers length of 13 mm is researched.
