Comparative Analysis for Building with Flat Plate Slabs and Void Slab using U-Boot Technology

Abstract

The flat slab is gaining popularity among architects. The flat plate slab provides a way for architect to achieve completely flat ceiling with no beam protrusion. There is also improvement in the construction speed and cost savings from using this system which requires only simple formwork. But when load acting on the slab is large or clear span between columns is more so it is required to increase the slab thickness; hence the self –weight of slab is increased due to increased volume of slab and also more amount of steel is required to resist this increased weight of slab. Voided slabs eliminate concrete where it isn’t needed and the subsequent weight reduction due to this eliminated concrete makes longer span possible. In this study the design process for flat plate slab is compared with voided slab lightened with U-Boot Beton through a design comparison of total slab area 40m by 40m having panels of 10m by 10m and also the deformation of both type of slabs is analysed by using ETABS software.
