Abstract

This work presents a numeric study using the Finite Element Method for castellated beams manufactured from Brazilian steel rolled I-sections, which collapse by web post buckling. After the beam analysis for the limit buckling state, other analyses were carried out, adding web post stiffeners in the region that would suffer the buckling. The results show significant influence of the stiffeners in the bearing capacity and in the collapsing mode presented in the analyzed beams.
