® BubbleDeck Design Guide The Biaxial Hollow Deck The way to new solutions ® BubbleDeck Design Guide 1 GENERAL BubbleDeck , a unique light, biaxial concrete slab, is generally designed using the conventional design methods for solid floor slabs in accordance with the current reinforced- concrete construction standard DIN 1045 (1988) or DIN 1045 (2001). The reduced intrinsic load is taken into account here, resulting in advantages for the individual static verifications. The required solid zones are defined using the calculated shear load-bearing capacity of the BubbleDeck without shear reinforcement. The advantages of BubbleDeck become apparent when it comes to the deformation calculation; bending-strength design; penetration design; load transfer to supports, walls and foundations; crack-reinforcement design; earthquake design; determination of resonant frequencies and determination of auxiliary supports during the construction phase. The hollow balls are first combined with upper and lower reinforcement mats and lattice trusses at the factory to form a BubbleDeck module. This module can already include the necessary lower bending reinforcement. If the reinforcement is a purely structural reinforcement, the module is referred to as a BubbleDeck basic module or ’Bubble lattice’. B u b b l e D e c k semi-precast modules are produced by pouring a concrete layer on the BubbleDeck module, acting as permanent formwork, at the factory. Both the ball grid spacings and the dimensions of the prefabricated modules are variable. The resulting flexibility ensures that the modules can be adapted to any floor plan and can
