The experience of many years of operation of large-panel buildings in various regions of our country has revealed a number of significant problems. They are connected both directly with the very design features of the buildings of the first industrial period, and with the quality of their manufacture, namely, deviations from the design solutions of structural elements in the manufacturing process. They did not affect the overall safe operation of buildings, but they did affect the performance of these structures. These include floor slabs for residential large-panel buildings, supported on two sides by a beam scheme, which, during the manufacturing process, received a deviation in the thickness of the protective layer of reinforcement from the design values in the direction of increase. This, in turn, during operation led to an increase in the deflection of floor slabs, in some cases more than the normative ones. Modern research has revealed the effectiveness of the use of alternative solutions - three-layer floor structures, which provide increased performance characteristics of panel buildings.
