Finite element analysis of cellular beam by load control method

Resumo

Cellular beams are of great interest due to their great flexural rigidity, high section modulus, excellent
height/weight ratio, economical and eco-sustainable construction, possibility of services through the openings of
the web and architectural aesthetic appearance. This study perform an approach to the processes of numerical
implementation via Finite Elements Method in cellular beams evaluating their elastoplastic behavior with focus
on the Vierendeel mechanism. The numerical model was calibrated against the experimental results of Warren [1]
and a comparative study is carried out with respect to the physical properties of the steel, allowing to understand
the advantages that high-strength steel can promote in this kind of structure.
