Nowadays, the need of high rise structure building with flat-slab is increasing over traditional RC frame building because of flexibility in construction, the free design of space, architectural function and reduction in construction time. Because of the absence of shear walls and deep beams, flat-slab structural building is significantly more flexible for lateral loads than conventional beam column building and that make the building deforms significantly and more vulnerable under seismic events. This paper is assessing of seismic behaviour of RC structure with flat slab and conventional RC slab on a full scale 16 storey representative of high rise building in different seismic regions. The analysis is done by using ETABS software performed based on Uniform Building Code 1997 (UBC 1997) for environmental loading and, American Concrete Institute (ACI 318-08) for consideration of design requirements for structural elements. Linear dynamic response spectrum analysis will be used on the structure. The seismic behaviour such as storey displacement, storey drift, storey shear for conventional RC frame and pure flat slab have been studied and analysis results are being compared in the different seismic zones.
