difference bubble deck slab and solid slab

1 : Section of Bubble deck slab - ResearchGateIn slabs, the depth of compressed concrete is usually a small proportion of the slab depth and this means that it almost always involve 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 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 ...

stresses in Solid slab Vs Bubble deck slab - ResearchGateLai 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 ...

All of the bubble deck versions come in three forms-. Filigree elements, reinforcement modules, and finished planks. For all types of bubble deck, the .... solid slabs shear is also a major concern for which several groups have performed tests on the shear capacity of bubble. deck slabs in various situations. In case of all flat plate systems, the floor to column connection is a area of high shear.

Structural behavior of bubble deck slab (PDF Download Available)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.

BubbleDeck - Voided Reinforced Concrete Slab - SlideShare12 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: ...

Structural Behavior of Bubble Deck Slab - ResearchGatethe 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 ...

What is the difference between a deck slab and a solid slab ...In my opinion, the term deck slab is associated with the Bridge engineering. The slab on the top of a bridge which inturn supports the carriage way is called as the deck slab. The term solid slab is used to denote that it's not hollow .
