A STUDY ON FAILURE OF BEAMS IN TERMS OF FORMATION OF CRACKS

Abstract

This research effort comprises examining beam failure and specifically fracture formation. Two retrofitting methods, wrapping technique and steel jacketing procedures, are employed to repair the cracks. The materials used to cast the beam are selected in compliance with the IS Code. The beam has dimensions of 150mm x 200mm and a span of 1500mm. M25 concrete is used, while Fe415 TMT bars are used for the steel. All beams are tested to the first fracture condition first. The shattered beams received five forms of retrofitting or restoration. For their rehabilitation, a Wrapping Method using GFRP of 225GSM, 400 GSM, 300 CSM, and Jute Fiber was employed. The repaired beams were subsequently put through rigorous testing until they failed. The ultimate load obtained from the experimental test is compared to the theoretical calculation for control Specimen in Limit State Design Method using the clauses supplied in IS 456-2000 code to cross-check the experimental work. The testing results were utilized to compare the Ultimate Load Carrying Capacity and Deflections at that Load for each of the five Retrofitting Methods with the Control Specimen. As a consequence of the results, the conclusion was reached.
