Abstract:

The application of a high-rise flat slab system is not studied in depth for symmetric and asymmetric building structures. This article focuses on a comparative study of flat slab systems for various cases of symmetric and asymmetric building structures. The base shear and story displacement for the considered cases are obtained using ETABS. Quantities of concrete and steel are calculated using ETABS & RCDC, followed by cost calculation. For investigating the effectiveness of a flat slab system, a comparative study between regular beam-slab structure and flat slab structure (with & without drops) is carried out. It is observed that the use of a flat slab system reduces the base shear and concrete weight of the building. Also, the cost of the building with a flat slab system is observed to be increasing compared to regular beam-slab buildings due to an increase in steel weight.
