The invention of a new type of hollow core slabs was a breakthrough at the turn of 20th and 21st centuries. Bubble deck slab Technology is a method of eliminating all concrete from the middle of a floor slab, which is not performing any structural function, thereby dramatically reducing structural dead weight. In this technology it locks ellipsoids between the top and bottom reinforcement meshes, thereby creating a natural cell structure, acting like a solid slab. High density polyethylene

By introducing the gaps leads lighter slab which reduces the loads on the columns, walls and foundations, and of course of the entire building. The advantages of the bubble deck slab are less energy consumption both in production, transport and carrying out, less emission of exhaust gases from production and transport, especially CO2 .The aim of this paper is to discuss about various flexural behaviors of two-way Bubble Deck slab such as ultimate load capacity, service load deflection, concrete stress distribution and crack pattern by using a model in ANSYS. Along with that various properties of bubble deck slab was also discussed based on the studies carried out on abroad.
