Analytical Study on Behaviour of Different Shapes in Voided Slabs and Voided Beams

Slab is largest member which consumes concrete and when load acting on the slab is large or clear span between columns is more, the slab thickness is increasing. It leads to consume more material such as concrete and steel due to that, selfweight of slab is increased. To avoid these disadvantages various studies are carried out and researchers suggest voided slab system [1]. To reduce the concrete in center of the slab by using hollow recycled plastic balls. High density polyethylene (HDPE) hollow balls replace the ineffective concrete in the center of the slab, thus decreasing the dead weight and increasing the efficiency of the floor. The advantages are less energy consumption both in production, transport and carrying out, less emission exhaust gases from production and transport, especially CO2 [2]. The aim of this paper is to discuss about the comparison of conventional slab and voided slab and also conventional beam and voided beam by using ANSYS software.
