surface, so there is no sensible difference between the behavior of a solid slab and bubble deck slab. In 2012, Prabhu Teja, P Vijay Kumar studied the durability of bubble deck slab and is explained on the basis of creep and shrinkage. A bubble deck element with two spherical hollows was compared with a solid concrete block of the same dimension and of the same concrete. The difference between the shrinkage strains of these two was measured. The results show that bubble  【Get Price】

Two variants of bubbledeck were entered into the comparison. The result was clear – the bubbledeck building was significant less expensive than the traditional system. The total savings was in the order of 20 %. Report from AEC Consulting Engineers Ltd. / Professor M.P. Nielsen - The Technical University of. Denmark – Enclosure H2.

BubbleDeck? - Voided Reinforced Concrete Slab - SlideShare

12 May 2016 The main difference between a solid slab and a voided biaxial slab refers to shear resistance. Due to the reduced concrete volume, the shear resistance will also be reduced. For a voided biaxial slabs with spheres the shear resistance is proportional to the amount of concrete, as the special geometry shaped by the ellipsoidal voids acts like the famous Roman arch, enabling all concrete to be effective. 6. The main structural consequences of bubbledeck system:  【Get Price】

the material or concrete consumption for the floor in comparison with a solid concrete floor of the same thickness. The saving on weight obtained in this way has the result that a. bubble deck slab floor can provide the required load-bearing capacity at a smaller thickness this leads to a further advantage, resulting in a saving of 40 to 50 % of the material consumption in the floor construction. This is not the last of the advantages of the bubble deck slab floor system: because of the lower  【Get Price】

Lai noted that the bubbledeck system was applicable for this application but further studies on a variety of bridge layouts were required to determine fully the feasibility of this system in bridges.Teja et al. (2012)performed finite-element analysis of bubbledeck slab systems using SAP2000 and compared the voided-slab system with solid slabs. This study showed that bending stresses, deflections, and shear resistance are slightly different than those for solid-slab systems, in the range  【Get Price】

8 Apr 2017 Shear ? The main difference between a solid slab and a voided biaxial slab refers to shear resistance. Due to the reduced concrete volume, the shear resistance will also be reduced. ? Near the columns, bubbles are left out so in these zones a bubble deck slab is designed exactly the same way as a solid slab. Shear resistance of bubble deck slab is 0.6 times the shear resistance of a solid slab of the same thickness . ? In practice, the reduced shear resistance will not  【Get Price】

21 Dec 2017 A. Flexural Strength. bubble deck slab is conceived to omit a significant. volume of concrete (compared to a solid slab) in the central. core where the slab is principally un-stressed in flexure [3]. In. slabs, the depth of compressed concrete is usually a small. proportion of the slab depth and this means that it almost. always involves only the concrete between the ball and the. surface so there is no sensible difference between the. behavior of a solid slab and bubble deck. 【Get Price】
