STRENGTHENING OF STEEL SECTION BY USING FRP SHEET.

Abstract

Fiber reinforced polymer (FRP) sheets are widely used to repair the element of steel structures in rehabilitation. Many research has done in this techniques. Application of this strip to increase the strength of element and it is effective option to increased loads carrying capacity of section and can be repair due to corrosion. FRP strengthened section increase the initial cracking time and reduce the cracks, it also extend the fatigue life. The method used in the research work were flexural tests and the work form of similar studies on the strengthened steel beams. BFRP and GFRP sheet and epoxies of diverse material properties are bonding to the tension, compression and both flanges of I beam section and testing for four point load. In this study we create the model using ANSYS v.12.0. Maximum deflection of beam in ANSYS model and compare to the actual tested beam
