Steel Fibre Reinforced Concrete Beams with Externally Bonded FRP Laminates
Keywords:
GFRP, Regression analysis, SFRC, Strengthening.Abstract
This paper presents regression equations for predicting the performance characteristics of steel fibre reinforced concrete beams strengthened with glass fibre reinforced polymers (GFRP) laminates. A total of four beams of dimension 150mm x 250mm x 3000mm were cast and tested to study the effectiveness of GFRP on steel fibre reinforced concrete beams. A fibre volume fraction of 1% was used in this study. Beams were strengthened with UDCGFRP laminates of 3mm and 5mm thickness. All the beams were subjected to two-point loading and tested upto failure. Deflections were measured through appropriate instrumentation at all stages of loading. The GFRP strengthened SFRC beams exhibit increased strength and composite action until failure.
