In general, the slab is designed to resist vertical load. However, as people are getting more interested in residential environment recently, noise and vibration of slab are getting more important factors to consider. In addition, as the span is increased, the deflection of the slab is also increased. Therefore, the slab thickness should increase. Increasing the slab thickness makes the slabs heavier, and will increase column and foundation sizes. Thus, it makes buildings consume more materials. To reduce the quantity of materials used, slabs with lighter weight had to be introduced. Hence in the present study, we have made an attempt to analyse the precast closed channel slabs. The reinforcement for the flange of the channel slabs was provided with the welded mesh of size 2.2mm diameter with 32mm x32mm spacing whereas the reinforcement in the web was varied. The varied web reinforcement’s are2.2mm diameter with 32mmX32mm spacing double layered welded mesh, vertical bars 6mm diameter HYSD bars spaced at 50mm c/c and vertical and diagonal bars of 6mm diameter bars spaced at 100mm c/c. It is found that Closed Channel Slabs perform better than Conventional Slab.
