Comparative Study of Flat Slabs and Waffle Slabs Structures Using E-Tabs on Different Earthquake Zones in India

Abstract

This study looks at the seismic performance of flat slab and waffle slab structures in various earthquake zones in India, utilizing ETABS for structural analysis. Flat slabs are often used in modern construction due to their advantages in weight reduction, construction speed, and cost-effectiveness, whereas waffle slabs provide flexibility, rapid construction, good vibration control, fire resistance, increased load-carrying capacity, and safety. The study works on a G+6 commercial building, analyzing variables such as base shear, storey drift, axial force, and displacement to assess the structural behaviour, performance, and seismic resistance of both slab systems. The study seeks to provide a thorough understanding of the seismic problems and performance of flat and waffle slabs in India's various earthquake zones.
