Comparison of Seismic Response between Flat Slab Building and Regular Frame Building

? In today’s world flat slab construction activity is growing due to many advantages it posses in terms of architectural flexibility, use of space, easier formwork and shorter construction time. From functional aspect a flat-slab RC frame building is more efficient than a beam-slab R.C. frame building. So, construction of flat-Slab building is increasing also in high seismic zone. In the present study, the seismic behaviour of flat slab building is carried out. For this purpose linear analysis of flat slab building and regular framed structure building has been carried out. The comparison shows that the flat slab buildings have low base shear capacity and large deflection. Also linear analysis of flat slab building with shear wall and regular framed structure building with shear wall has been carried out. It is found that the performance of flat slab building under seismic load improves much better with the use of shear wall.
