A popular form of concrete building construction uses a flat concrete slab (without beams) as the floor system. This system is very simple to construct, and is efficient in that it requires the minimum building height for a given number of stories. The flat slab system is currently widely used in construction. It permits flexibility in architecture, more clear space, low building height, easier formwork, and shorter construction time. However, Flat slab building structures are significantly
more » ... e significantly more flexible than traditional concrete structures as beams are not present. They are more vulnerable to earthquakes. The objective of this research is to investigate the behavior of flat slab multistory G+19 building in four different cases as I) flat slab structure without shear wall. II) Flat slab structure with shear wall at core of the building. III)Flat slab structure with shear wall at corners of the building IV). Flat slab structure with shear wall at side centers of the perimeter boundary of the building. The lateral behavior of a typical flat slab building is evaluated by means of dynamic analysis through linear time history analysis method using ETABS software. The efficiency and serviceability under Indian standard code in seismic zone 'V' been observed for each defined model and compared the values with international codes.
