Abstract In order to increase a stiffness of cold-formed steel (CFS) elements it is practised to built-up the cross-section.In the analysed case, a main element is strengthened by adding extra chord in contact partially along the column.This additional chord acts as a longitudinal stiffener connected with the citronella horse shampoo main section by series of bolts.Authors check whether rules applied over the years, here for hot-rolled elements, can be indiscriminately used in the analysed CFS element.The aim of this study is to experimentally and computationally recognize the normal stress distribution in axially compressed CFS built-up column chords and to evaluate the element load-bearing capacity.
