Recently in the research publications an information about a new type of suspended straight‐line 3‐hinge roof structures has appeared. In this sources it was stressed that straight‐line elements is easy to manufacture and erect, roof decking service conditions are good. In the world building practice during last 30 years very effective composite structures were introduced, even hollow concrete‐filled steel tubular members. At this time no information about the application of such members for suspended roofs was obtained. In some sources very simple straight‐line suspended roofs structures were analysed, and for these shapes an effective centrifuged hollow concrete‐filled steel tubular members may be successfully applied. These members do not require additional roof stabilisation. These composite ropes may be attributed to the elements of final flexural stiffness, and they are effective and simple to decrease deflections of a suspended roof. However, for such composite ropes methods of their calculations must be developed. Investigations made into the deformation properties and methods of deflection, definition of straight‐line circular hollow concrete‐filled steel tubular members allows to declare a possibility of useful application of such members as ones of final flexural stiffness in suspended roof structures.
