Abstract
Flange-web conjunction of pultruded I-beams has a significant effect on their ultimate strength and other properties. It is important to understand and predict the behaviour of pultruded I-beams with various flange-web connections. This article presents the simulations of mechanical performance of pultruded I-beams with various flange-web connections using finite element analysis. The flange-web conjunctions are parameterized by the radius of the transition fillet between flanges and web and the mechanical properties of the composite filling the connection area. A flange-web conjunction enhanced by strips is also considered. The variations in stiffness, maximum compressive and tensile stresses and the critical buckling load of the beams with various flange-web connections are evaluated. The results show an effective approach to improve the flange-web connection.
