Abstract : Cellular beams are those beams which have circular shaped openings in its web portion. Use of cellular beams has become very popular now days due to its advantageous structural applications. This is due to increased depth of section without any additional weight, high strength to weight ratio, their lower maintenance and painting cost. Therefore, considering the structural performance of the beam, the failures found in the cellular beams, the Vierendeel mechanism and the local instability (buckling) at the openings and the web-posts respectively, deserve special attention as these are the most common failure modes. In this paper, investigation has been carried through a numerical analysis, the behaviour of steel cellular beams without stiffeners at right of concentrated loads or support reactions, taking into account material and geometrical non-linearity. This analysis is designed to predict through a Finite Element modeling, the Vierendeel effect and the web post buckling due to the compression force by estimating the corresponding ultimate loads. Keywords - cellular beams, non-linear finite element modeling, Vierendeel effect, web-posts buckling, ultimate load.
