Analysis of GFRP-reinforced beams in enhanced SCC

Prithiviraj Chidambaram, Saravanan Jagadeesan

Abstract

This study investigated the flexural behaviour of glass fibre-reinforced polymer (GFRP)-reinforced beams with two different ratios (0.68 % and 1.03 %) using traditional Self-Compacting Concrete (SCC) and SCC with 30 % Ultrafine Slag (UFS). The study analysed crack patterns, failure modes, load-deflection responses, strains in the concrete and reinforcement, and the influence of the reinforcement ratio and SCC compressive strength. The results indicated that under-reinforcement led to the rupture of the GFRP, balanced reinforcement resulted in bar and concrete failures, and over-reinforced beams mainly experienced compression zone concrete crushing. This study compared the ACI Flexural Design Guidelines (2015) with the experimental data.
