Dynamic Behaviour of Flat Slabs

The buildings are encountered by earthquake and wind forces throughout their life. These lateral forces produce vibrations in all the elements of the building. To cater the floors of large populated halls like restaurants, concerts, theatres etc, large column spacing is required. Due to the large span, tremendous vibrations are induced in these floors, which are controlled by the use of flat slabs. The amount of vibrations depends upon the material, span, thickness, and damping of the flat slabs. To control these vibrations, parametric investigation is carried out to study the response of flat slab under different exciting/frequencies while changing the end conditions. In this study, optimum parameters are obtained to control the deflections and vibrations of flat slabs in the buildings.
