BubbleDeck is a true biaxial slab and behaves like a solib slab, both in aelastic and plastic modes.

Common calculation methods like Linear Elastic and Yield line methods are applicable.

Due to its optimised geometry, ALL concrete in the slab an be taken into account in calculating any types of forces.

Since all concrete in the slab is active, the theoretical shear resistance is proportional to the amount of concrete. Hence, the shear capacity is 65% compared to a solid slab with the same slab thickness.For practical applicability including safety, a factor of 0.6 should be used.

A solid slab can only carry app. one third of its own weight, and has problems with long spans due to its high weight. BubbleDeck solves this problem by eliminating 35% of the concrete, while retaining the strength.

Hence, a BubbleDeck slab has the same applied load capacity with only 50% of the concrete required for a solid slab, or with the same slab thickness has twice the load capacity using 65% of the concrete.
