Static Analysis of Steel Plates and Sections Retrofitted with FRP Plates by Finite Elements Modelling

Nowadays the use of FRP composites for strengthening steel structures has been considered by researchers. In present study, The maximum deformation of steel plates and structural sections before and after strengthening by GFRP plates was evaluated by modelling and static analysis using ABAQUS finite...
