Assessment of Response Reduction Factor of Flat Slab Structures by Pushover Analysis

Abstract

India is rapidly developing in every aspect now. As a result of which number of smart cities are now arising. while building such smart cities major role is played by infrastructural development. In this infrastructures, speedy and economical constructions are expected to make them more effective. Among such effective construction systems, Flat slab system is the one and is being widely applied on large scale. Flat slabs are thin solid reinforced concrete slabs which are supported directly by columns without beams. Flat slab system is now well adopted for constructions of high rise multi- storied commercial, residential, institutional buildings. They have adventitious constructive, architectural and economical features including easier formwork, speed of construction, spaciousness, etc. The purpose of this project is to study the seismic behavior of Flat Slab Structure for different seismic zones by assessment of Response Reduction Factor using Pushover analysis. Response reduction factor is the factor by which intensity of seismic waves produced during earthquake (maximum elastic base shear) can be reduced to calculate the design base shear. In the project parameters such as base shear, shear and bending stresses and deflection check in flat slab structure are examined by using ETABS Software.
