For column buckling analysis is a critical area of study to determine overall section capacity subjected to axial load. FRP columns are manufactured using fiber and matrix composite lamina. Many researchers have studied the axial capacity of simply supported pultruded FRP column for various types of loadings. In this paper an attempt has been made to study the axial capacity of column subjected to point load for WF (wide flange) & NF (narrow flange) section. The validation has been made with experimental data. Further the parametric study has been carried out to study the mode of buckling with different length subjected to axial loads. The effect of ratio like bf/bw is also studied. The effect of slenderness on global lateral torsional buckling and local flange buckling under uniform axial loading is also studied.
