From functional aspect a flat-slab building is more efficient than a R.C. frame building. So, construction of Flat-Slab building is increasing also in high seismic zone. Sometimes international building codes remain silent about the seismic response of flat slab buildings. In this paper the response of Flat-Slab building and a normal symmetric /5(6). The Flat slab floor system pro mises a world of benefit s over the traditional beam-and-slab floor system; however, there are some d rawbacks with this floor . Commercial building with Flat slabs is taken for analysis. The salient feature of the building is: Type of slab Flat Slab No. of stories G-2, G+7 Shape of the building Asymmetrical Depth of the slab mm Seismic zone II, III, IV Imposed load kN/ Floor finishes .

Layout of building A floor slab in a building where stability is provided by shear walls in one direction (N-S). The slab is without drops and is supported internally and on the external long sides by square columns. The imposed loading on the floor is 5 KN/m2 and an allowance of KN/m2 for finishes, etc. fcu = 40 KN/m2, fy = KN/m2. The main difference between flat slab & conventional slab-beam system is that the one is directly supported on the column while another system has a beam for support. The load is transferred directly from slab to column in the flat slab. In conventional slab-beam system, the load is transferred from slab to beam and ultimately beam to the column. The flat plate is a two-way reinforced concrete framing system utilizing a slab of uniform thickness, the simplest of structural shapes. The flat slab is a two-way reinforced structural system that includes either drop panels or column capitals at columns . Flat slab system is an important division of concrete floor system. A civil engineer must know all the aspects regarding the flat floor system. Here, we have tried to gather various reading materials available in the web about flat slab floor system in one place. These materials are originally located at different websites.
Excerpt from Tests of a Flat Slab Floor of the Western Newspaper Union Building Acknowledgment of valuable aid received in carrying out the test is made. The portland cement association furnished the labor for preparinglfor the test and for hauling the loading material and loading and unloading the ﬂoor.

A flat plate floor system is a reinforced concrete frame system with a uniform thickness that is supported directly over the columns or the load-bearing walls. The flat plate floor system is a common floor construction type employed in the construction of the building. The important features, construction and the advantages of employing a flat [ ]. The floor system is supported by columns of size mm ´ mm. Floor to floor distance is m. Use M20 concrete and Fe steel. 3. For the flat slab system of size 6 m ´ 6 m provide suitable drop and fix up overall dimensions. The floor system is supported by columns of size mm ´ mm, the floor height being m.
