Parametric Study of Flat Slab Structure with Soft Storey against Earthquake Forces

The demand of business activities in the existing and developing cities is increasing tremendously. Due to this there is a hike in the availability of land for carrying business activities. So, the scarcity of land in these cities led to the development of high rise buildings. The requirements of the commercial buildings are faster construction, flexibility in room layout, less building height. Flat slab construction places no restrictions on the positioning of horizontal services and partitions and can minimise floor-to-floor heights when there is no requirement for a deep false ceiling. Flat slabs have a lower stiffness in comparison to a beam-column floor plan which can lead to relatively large deflections during earthquakes. In the present study a parametric investigation was carried out in order to identify the seismic response of systems flat slab building subjected to earthquake forces. A 9 storied structure was taken for the analysis to identify the seismic response and therefore strengthening by providing shear wall at various locations to reduce the lateral resistance of the structure.
