Abstract

Slab is one of the largest consuming concrete member to carrying a load. A slab being the essential part of the building and should be successfully intended and utilized. The slab requires more concrete, while constructing the co2 emission is high and it leads to global warming, hence has to be optimized. Concrete plays a major role in the construction field. The usage of concrete is high in slab construction. Multiple elements transferring and resisting external loads throughout the structure. The vertical loads acting on the slab can be transferring to the beam and then column .The gravity path is depends upon the type of slab is used and also we consider the load transfers from the structure only on the column portion not throughout the slab. While reducing the dead weight of the slab the entire construction weight is least and cost saving is also elevated. Therefore we reduce the concrete in centre of the slab by using cast-off balls. Bubble Deck slab is one of the recently developed prefabrication construction technology functional in many engineering projects in the world. In Bubble Deck slab either can use steel balls or hollow balls will be recycled plastic and therefore it reduce the dead weight of the slab and also eliminating the concrete part which does not contribute to the structural concert. The model is analyzed by ANSYS software with appropriate support conditions as with the experimental setup and providing uniformly distributed loading in the bubble deck slab and in conventional slab. The stress and deformation results were evaluated and compared the bubble deck slab with conventional slab were observed using finite element analysis. At last the comparison has been made for Bubble Deck Slab with the Conventional slab over its self weight. From the evaluation of these results, Bubble Deck Slab gives better performance than that of the conventional slab. M. Ranjitham | N. V.
