Abstract- Flat slab building structure, possesses major advantages over traditional slab-beam-column structure .due to the absence of beams, it can accommodate reduced floor height , easier from work ,lesser construction time ,and better architectural function . however the structural effectiveness of flat slab construction is hindered by its vulnerability even under seismic events of moderate intensity .the flat slab structures are significantly more flexible than traditional concrete frame as it cause excessive deformation which in turn cause damage of both structural and non- structural members under seismic excitations . therefore additional measures for the design of these structures in seismic regions are needed such as a possible combination with other seismic resistant structural system .In the present study an investigation is carried out in order to identify the seismic response of flat plate and flat slab id structural system ,consisting of with or without core wall, at different locations ( center , bottom left , bottom right , top left and top right)and shear wall at periphery of building compared with grid slab structure.The analysis is carried out by using E-Tab V9.7.4,a commercially available structural analysis and design software .results of the study are deemed very useful in the selection and preliminary design of the basic structural system.

Keywords: Base shear, Time period, Storey drift, Displacement, Static and Dynamic analysis (EQX,EQY).
