ABSTRACT
A new type of cellular beam has been developed by ArcelorMittal (AngelinaTM beam) composed of regularly spaced sinusoidal openings (Fig. 1). In fact, changing the opening shape has an impact on the behavior of the beam and mainly its failure modes. Thus, experimental tests have been conducted on three full scale cellular beams with sinusoidal openings at Blaise Pascal University (Clermont-Ferrand) in order to evaluate and understand their complex behavior at ultimate limit state.
