Abstract
This research presents the analysis and the low-weight optimization design of the cold-formed battened built-up column of the crane runway beam by the Marine Predators Algorithm (MPA). The objective function (the total weight of the battened built-up column) workflow uses slenderness and the geometric parameters of the channel section and batten plates as variables. This study uses the global stability of the built-up column, the buckling check of the built-up column about the material axis and non-material axis, the buckling and the strength check of the chord of the built-up column, the strength check of the batten plate of the built-up column, the strength of the batten plate's weld connections, as well as geometrical recommendations and limitations as the constraint functions. Achieved savings in column weight are between 38.66% and 51.66%, dependingly on the material and the number of batten plates of the considered example of the built-up column.
