Numerical Analysis of the Stresses and Behavior of Composite Castellated Beams

Resumo

This work has as main objective to analyze, through numerical modeling, the structural behavior of Composite Castellated Beams (CCB), with steel profile and reinforced concrete slab, in order to map the performance of the beams and the stress distribution for hexagonal castellated holes. For this, a detailed study of the CCB behavior will be done, then, based on the data obtained, a numerical modeling through the Finite Element Method (FEM) using the ABAQUS/CAE software was elaborated, and finalized with an extensive analysis of the behavior of the stresses in each type of beam modeled. This study is important because composite castellated beams are structural elements that have high strengths because they are the result of the application of various construction techniques. First, composite beams with steel profile and reinforced concrete slab increase the bending stiffness and resistance to stresses of the beam. Also, castellated beams have higher bending stiffness due to the height gain after their construction process. Therefore, the union of these techniques needs to be studied and analyze the stresses generated in the beam.
