Comparative Study of Bubble Deck Slab with Conventional R.C.C Slab

Abstract

Abstract: When designing a reinforced concrete structure a primary design limitation is the span of the slabbetween the columns. Designing large spans between columns often requires very thick slabs thereby increasing the weight of the structure by requiring use of larger amounts of concrete. Heavier structures are less desirable than light weight structures in seismically active regions because a larger dead load for a building increases the magnitude of inertia forces which the structure must resist as larger dead load contributes to higher seismic weight. A new solution to reduce the weight of concrete structures and increase the span of reinforced concrete is “Bubble Deck Technology''. Bubble Deck Slab is a futuristic method which can effectively eliminate all the concrete from the middle of slab by replacing it with high density polyethylene balls. In this technique reinforcement mesh acquires, allocates and attaches the balls at exact position and also stabilizes the lattice. By these techniques the structural weight can be reduced from 25% to 50%. The main aim of our study is to compare bubble slab and conventional slab under cost analysis, stress and deflection. In our project, we designed both the slabs using AutoCAD and tested our design using Ansys software. The advantages are less energy consumption - both in production, transport and carrying out, less emission - exhaust gases from production and transport, especiallyCO2.
