Abstract
The results are presented of an investigation on the buckling behaviour of concentrically loaded thin-walled pultruded fibre reinforced polymer composite columns. Both open- and closed-web columns were evaluated. Finite element analysis and theoretical predictions are presented and correlated with experimental data. Good agreement was found between theoretical, analytical and experimental results. Also presented are guidelines for the determination of the bending stiffness and the critical buckling load for pultruded composite columns, and a discussion on the axial strength of unidirectional pultruded fibre reinforced polymer columns, together with the identification of different modes of failure. 18 refs.
