Abstract: Construction of slab element is one of the important structural members consumes higher concrete. It is necessary to optimize the use of concrete in slabs. Bubble deck slab is an innovative technique made up of high-density polyethylene hollow spherical balls. It eliminates the inactive concrete which is present below the neutral axis by replacing hollow spherical balls. The parameters like strength, stiffness, durability and structural integrity remain unchanged when compared with the conventional slab. It has advantages in terms of economy, reducing co2 emission, earthquake damages and structural dead weight etc. Bubble deck slab diminish the load coming on the columns, walls, and foundations. In this research work, simulation work has been carried out on bubble deck slab by varying the parameters such as void ratio and thickness of bubble deck slab at different support conditions under uniformly distributed load by using ANSYS. From this simulation work, the total deformation, directional deformation, and Von-mises stresses were assessed. It is been concluded that when the void ratio percentage was varied from 30- 50% for achieving high strength.
Keywords: Void Ratio, Size of the Slab, The Compressive Strength of Concrete, Type of Load.
