This paper deal, on example of aluminium alloy beam strengthened by using elements of steel, with theoretical analysis of the possibilities for composite action of beam formed from two materials with considerably different coefficients of thermal expansion. According to authors opinion conclusions lead to clear statement that such structures are possible as well that such solutions could have economical and serviceability sense, especially in field of structural engineering where exposing to temperature changes is limited to relatively small range. In case of aluminium and steel combination, for extreme temperature change used in structural engineering, advantages that are achieved are considerably higher than disadvantages, especially in cases where deformation is dominant condition.
