This paper focused on flexural behavior of steel I beams strengthened with carbon fiber reinforced polymer (CFRP) sheets and basalt fiber reinforced polymer (BFRP) sheets. The simply supported steel I beam in previous experimental work was modelled by using ANSYS finite element software. The parameters used in FEA are same as that of used in experimental work. Conventional strengthening technique for huge steel structures depends on enlarging the original steel section by welding additional elements such as steel plates or channels. In this conventional strengthening technique the dead load of the enlarged section becomes larger which may result in a reduction in its effectiveness and the added steel plates are also susceptible to corrosion if structure is situated in a corrosive environment. Also this technique requires heavy lifting equipment during the erection process. Due to these reasons considerable amount of research has been directed to the use of Fiber Reinforced Polymer (FRP) materials for strengthening and retrofitting of steel structures as FRP sheets are being used extensively from past two decades to rehabilitate concrete structures. Taking into account the various benefits of using FRP in strengthening process of structures it has become essential to study the flexural behavior of structural members, especially of steel structures, by making use of FRPs. Therefore, in this project work flexural behaviour of the steel I–beams using different types of FRP sheets namely carbon fiber and basalt fiber have been studied. The results obtained in experimental work have been validated from finite element model developed in ANSYS software.
