Theory
In principle, BubbleDeck® slabs acts like solid slabs. Designing is consequently like for solid slabs, just with less load corresponding to the reduced amount of concrete. Thorough investigations according to Eurocodes are made at universities in Germany, Netherlands and Denmark, concluding that a BubbleDeck slab acts like as a solid slab.
It is important to emphasize the differences in static calculations between different hollow slabs. While a true biaxial slab as the BubbleDeck system must be calculated as a solid slab, ribbed slab systems, like the U-boot system, consisting of a grid of orthogonal "I" beams, must be calculated as beams.
The BubbleDeck® technology is directly incorporated in national standards, such as the CUR in the Netherlands.

“Lucretius
Sings his great theory of natural origins and of wise conduct; Plato
smiling carves dreams, bright cells
Of incorruptible wax to hive the Greek honey.”
—Robinson Jeffers (1887–1962)
