Nowadays, more often than before, civil engineering designers are willing to use steel build-up members composed of single or doubled cold-formed chords interconnected using different mechanical connectors. This paper subject is an analysis of cooperation of a closely spaced built-up cold-formed chord interconnected with series of bolts that are located along the length of the member in a specific spacing. This distance along the length of the compressed member is a variable parameter of this project analysis. In order to perform natural scale experimental studies a model of a laboratory station has been designed and a build-up compression element was prepared. The numerical model of the closely spaced built-up member consists of shell elements. Computer FEM analyses including contact between elements and geometrical imperfections have been carried out. The influence of bolt series distance on element interaction nature is being studied.
