Analytical and Experimental Study on FRP Confined Concrete Column
B.Manjula and D.Thanagar
Abstract: Fibre reinforced polymer (FRP) is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass, carbon, aramid and the polymer is usually an epoxy, vinyl ester or polyester thermosetting plastic and phenol formaldehyde resins. FRP have been found to be particularly attractive for applications involving the strengthening and rehabilitation of structures. In this work an attempt has been made to develop a 3-D finite element model of FRP confined concrete column using ABAQUS software. A Drucker-Prager Plasticity model is used for concrete and orthotropic elasticity model is used for FRP. Also a parametric study has been carried out to evaluate the effect of number of FRP layers and corner radius on ultimate strength of concrete short columns and also validate the analytical study. A study was carried out on square column of cross section 125 x 125 mm with height 300mm with varying corner radius such as 15mm, 25mm, 35mm and 62.5mm along with control column were cast with M20 grade concrete. Confinement provided as single layer and double layer for the column by using E-Glass fibre chopped strand mat of density 450g/m2.The columns were tested under axial compression load up to failure. From the test results, the ultimate load were compared with the analytical results.
