Abstract
Precast concrete has been used for many decades with optimized consumption of concrete and reinforcement. The use of monolithic reinforced concrete in the Russian Federation cannot be called balanced in terms of its material consumption. One of the design ideas for creating lightweight slab reinforced concrete structures in monolithic construction is the BubbleDeck technology. Spherical bushings are located in places of the least stresses in the structure, which leads to a significant reduction in the own weight. The article presents the results of assessing the strength, stiffness and crack resistance of a reduced model of a reinforced concrete slab in comparison with similar parameters of a solid section slab.
