An Experimental Study of Flexural Behavior of Bubble Deck Slab

Bubble Deck Slab(BDS), RC Conventional Slab.Abstract
Reinforced concrete slabs are one of the most common components in modern building construction. Reinforced concrete slabs with plastic voids are a new and innovative type of structural concrete slab system developed to allow for lighter self-weight of the structure while maintaining similar load carrying capacity of a solid slab. Plastic voided slabs are capable of reducing the amount of concrete necessary to construct a building by 30 percent or more. This reduction can be beneficial in terms of financial savings as well as building performance. This report examines a flexural capacity of two-way reinforced concrete slab with spherical voids in comparison to conventional reinforced concrete slab. The conventional reinforced concrete slab is designed as per the Code provision of IS: 456-2000. For the same depth of slab, 35mm and 40mm diameter spherical voids are created at different spacing at the center of the slab to create voided slab. The slabs are analyzed for different loading and boundary conditions. The geometry of all the slabs was constant 1000x1000x70 mm. The slabs are subjected to nine point bending load/UDL.
