Parametric Study on Dynamic Behaviour of Waffle Slab

Nowadays, Multistorey Building which include Fitness centers, Parking garages, Super markets, offices, Food centers are trending worldwide. In which, Simple activities like walking, running skipping, jumping can generate vibration in the slab. This vibration can cause inconvenience in persons and questions about safety of structures and risk of collapse that is determined by its intensity of vibration. The objective of this paper is evaluating the behaviour of reinforced concrete waffle slab due to human rhythmatic activities and resonance. Waffle slab are modeled by element meshing method with ETABS with different plan aspect ratio. Here two types of dynamic analysis are performed: free vibration analysis for obtaining natural frequencies and mode shapes and forced vibration analysis to obtain Maximum displacement.
