Composite acti on is a structural solution that has increasing importance due to the significant potential in performance improvement of structural elements, and simplification of the construction technological process. Although steel - concrete composite structures are no w in use for more than a century, certain forms of composite action are still not sufficiently dealt with in modern standards. One of such solutions is a composite truss system, which is the subject of this paper. This type of construction has advantages t hat can be utilized in medium and large spans, and in comparison to steel trusses has a lower height. When it is combined with trapezoidal sheets for composite slabs it provides a number of practical advantages. Relevant literature reports that with the us e of this system load transfer efficiency increases by 20% to 30%, and the shown design example of a building for commercial purposes in composite and non - composite versions supports such a claim.
