Annotation: The article deals with the issue of rational choice study estimated geometrical parameters of the combined metal structures and analysis of the results of research. The use of these structures presents a major opportunity to create surfaces that are easy, high technical-economic indicators, architectural expression. Using the calculation method of adjustment of SDS combined metal construction ensures equality of stresses in the calculated cross section of the beam stiffness. It is shown that rational combination design as a whole depends on the stiffness of the suspension towers supporting system and the topology. It is proved that the mass of continuous beam stiffness at intermediate elastic supports, compared with a beam on two supports to span 60 m, rapidly decreases in the presence of up to three towers. Rational angles podkosov, strands and cables composite structures relative to their weight in the range of 30–60°. The research results are put into practice building, bringing economic benefit was obtained 6 118 thousand uah.
Keywords: rational combination design, equi-stress, suspension towers, regulation, rational angles.
