The investigation on non‐composite asymmetric cellular beams is limited. Previous research focused on the behavior of asymmetric steel cellular sections by using different root beam for the top tee and the lower tee section. Moreover, asymmetric beams can be designed in different concepts as in the case of this study where the same root beam is used for top and bottom tee of the non‐composite asymmetric cellular beams. This research presents a numerical study on the structural behavior and resistance of symmetric and asymmetric non‐composite cellular steel beams using IPE sections. Five cellular steel beams were analytically modeled and verified using experimental work from published research. The study was carried out using three‐dimensional finite shell element modeling of I‐shaped cellular steel beams with a broad spectrum of cross‐sectional dimensions, unrestrained lengths, web perforation configurations, application of loads and various steel grades. Geometrical and material nonlinear analysis was performed by using ABAQUS software. The results of asymmetric sections showed notable improvements on the small parent sections failing under vierendeel mechanism while the results for the deeper sections showed the opposite.
