This research aims to analyze the stability behaviour of castellated beams and compare it with regular hot-rolled profiles.
Conducted numerical analysis of castellated steel beams
Investigated boundary conditions affecting elastic critical moment
Compared results with regular hot-rolled profiles
Used standards CEN/TR 1993-1-102:2025 and EN 1993-1-1:2022
Identified influence of boundary conditions on stability behaviour
Found that castellated beams are susceptible to local failure modes
Demonstrated potential for improved resource efficiency in design methods
