Abstract: The stress-strain state of the cyclone heat exchanger independent stack-frames for various types of structural schemes during construction in a seismic area has been investigated. The dynamic properties of a structure, its stress-strain state are largely determined by the parameters of the base and the method of foundation the structure. With an increase in the rigidity of the base, the seismic forces in the structural elements increase by an average of 40 %. The diaphragm setting (bonds) allows significantly reducing the design forces in the frame elements (bending moments – 4–15 times, longitudinal forces – 1.5–2.0 times) and greatly simplifying the reinforcement of the most stressed members and structural components. In reinforced concrete independent stack-frames, the forces in columns of own weight is five times higher than those from process duty. The large weight of the structure causes significant seismic forces in the structure. Nominal case conditions from seismic in the independent stack-frame with a metal frame is 3 to 4 times less than in the independent stack-frame with a reinforced concrete frame and do not exceed the effort from the wind loading. Reinforced concrete and metal frames have a comparable cost. In the conditions of the home construction industry, the reinforced concrete frame is more technological, it is possible to create the design of any forms and make changes to the project practically painless. Designing is easy to conduct in parallel with construction. An analysis of all available information on the structure showed that the most rational structural design of the structures is a reinforced concrete frame with a diaphragm in the central span of the side faces of structures with a foundation in the form of a plate on a natural base.
