Buckling analysis of cantilever pultruded I-sections using

For steel beam buckling analysis is a critical area of study to determine overall section capacity subjected to bending. Pultruded I-beams are manufactured using fiber and matrix composite lamina hence is usually orthotropic compared to conventional steel I-beams. Many researchers have studied the buckling characteristics of simply supported pultruded FRP beams for various types of loadings. In this paper an attempt has been made to study the buckling characteristics of cantilever beam subjected to point load at free end 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 effect of fiber orientation along with fiber volume fraction on critical buckling loads.
