Abstract The present study aims to investigate the behavior of steel–concrete composite cellular beams subjected to hogging moment. A finite element model is developed and validated via ABAQUS software. The I-section dimensions, free span, hogging moment distribution, and the key geometric parameters of cellular beams such as the opening diameter and web post width are varied. In total, 360 models were analyzed. The results are compared with analytical procedures. It was concluded that there were divergences between the comparisons of numerical results with the analytical models. The key parameters of the cellular beams showed a significant influence on the resistant capacity, as well as the failure mode of the models. The I-section dimensions were the parameters that had the greatest influence on the load carrying capacity of the models.
Highlights The assessment of the structural behavior of steel-concrete composite cellular beams under hogging moment are presented. These beams can reach the failure by the Lateral Distortional Buckling (LDB), local buckling modes or by their interaction. The gap of studies that investigated cellular composite beams subject to hogging moment is evidenced. Some parameters that have a significant influence on the resistant capacity of these structures was investigated. The standard procedures do not address LDB strength of composite cellular beams but the standard adaptations were evaluated.
