Analytical modelling for confinement of high strength concrete Columns with glass fibre reinforced polymer wrapping

Fibre reinforced polymer confined columns have been developed for new construction rehabilitation of concrete structures such as piers or piles in civil engineering field. The design oriented confinement model predominant in designing FRP confined concrete columns. The design model is directly based on in interpretation of experimental result. In this study one model is presented for reinforced concrete columns externally reinforced with fibre reinforced polymer wraps using finite element method adopted by ANSYS software. The finite element model was developed using for concrete and the three dimensional layer elements for the fibre reinforced polymer composites. The result obtained from those finite element analysis results were compared on the experimental data for respective concrete column with different conditions from researcher. From the analysis load deflection, stress strain relationship, performance characteristics of GFRP wrapped column were also to be studied. The prediction of ANSYS model agreed with the experimental results.
