4. Key findings
In the construction industry about 70% of the civil construction is achieved through the application of industrial technologies in Russia. Structural systems of civil buildings have undergone significant changes in the direction of the resource. However, further improvement of such structural systems is not exhausted [6, 15, 21]. For example, in the practice of civil engineering apply constructive solutions to the building frame of the industrial panel elements [4, 10], including load-bearing longitudinal and transverse wall panels connected to the floor slab, self-supporting outer walls are applied. Disadvantages of constructive solutions are as follows: longitudinal and transverse wall panels are made of structural concrete. Structural concrete has a high consumption of materials and energy. Slabs have a high intensity, low sound insulation performance. The intermediate joints of exterior walls may be susceptible to freezing, as they are not insulated and should not have thermal protection [10, 19]. These disadvantages can be eliminated by creating and implementing new industrial energy-efficient and resource-efficient structural systems of FLYLO EXLOGLQJV >25í27@ RQ WKH EDVLV RI WKH UHVRXUFH FFOH ORZ-waste technologies (Fig. 1).
