In the study, three dimensional analytical models of G+20 story buildings have been generated and analysed using
CSI ETABS software version 2016. The earthquake zone III in India is considered for buildings during analysis. Here, the
analysis and design is done of G+20 story building with flat slab(with drops) and conventional slab system. In earthquake zone
the displacement and drift of the structures will be more so to have more stiffness to the structure shear wall is to be provided
therefore a study is made by comparing between conventional slab & flat slab (with drops) building. Comparison of various
parameters like story drift, story displacement, story stiffness and time period is done.
