Abstract: The primary goal of this work is to analyze, using numerical modeling, the structural behavior of Composite Castellated Beams (CCBs) made of I-steel profiles and reinforced concrete slabs. This work examines the performance of CCBs and the stress distribution around circular castellated holes. For this, a detailed numerical modeling through the Finite Element Method (FEM) using the ABAQUS/CAE software was elaborated. The results were analyzed, showing the behavior of the stresses in different circular holes of beams modeled. CCBs are important structural elements with high strengths. These strengths come from using innovative building techniques. CCBs with castellated steel profiles and reinforced concrete slabs have their height increased after construction. Castellated beams present higher stiffness without increasing the ratio of weight to length of the beams. However, the presence of holes generates complex stress states on the castellated steel beams used, and such states need to be studied for a better understanding of the behavior of CCBs.
