FINITE ELEMENT MODELING TO PREDICT FLEXURAL PERFORMANCE OF STEEL I-SECTION BEAM EXTERNALLY BONDED BY VARIOUS FRP FABRICS: A REVIEW

Use the fiber reinforced polymers fabric (FRP) in repair and strengthening of bridges, steel structure, etc. This article is review of literature available on flexural behavior of I-section steel beams with externally attached with FRP fabrics. It can be useful to decide which FRP sheet is best to use with steel beam to enhance flexural strength. Also this study comprises of cost comparison of Steel I beam strengthened by various FRP i.e. Basalt-FRP, GlassFRP and Carbon-FRP. This can be achieved by bonding various FRP sheet at bottom flange, top flange & two faces of web to steel I section beam. It was studied through experimental, analytical, numerical investigation. Most of work is done on carbon-FRP fabric attached to steel beam as compared with Basalt-FRP. Some literature studied properties of FRP, adhesive bond, and fatigue behavior. In experimental method, four point bending test was performed and model were analyzed using FE analysis. From this review, Carbon-FRP gives better performance of Steel I beam as compared with other FRPs.
