Behaviour of Waffle Slab, Flat Slab, Ribbed & Secondary Beam in a Multistorey Building under Seismic Response: A Review

The demand of multi-story Building is increases day by day. The purpose of building is mandatory things to design a building. The building may be residential or residential plus commercial. The new trend introduced the use of different types of slabs and structural engineers have the big challenge to work on it. The use of advanced slabs in building predominantly for the need of large span. The large span is needed for Flat slab, Waffle slabs & ribbed slab stands as a better & effective option for architects under the building required larger spans. The benefit is it covered least possible number of columns. Therefore, it is necessary to study about its structural behaviour. The paper consists of summaries report on different research papers based on use of different types of slabs such as flat slab, waffle slab, ribbed slab concept by different researchers. Some researchers also used the secondary beam with the normal slab to transfer the load of the structure effectively to the column. The review paper concluded that flat slab can be effectively used for the multistorey building. The use of waffle and ribbed can also be used with high rise & tall structure construction due to more resisting moment capacity of the slabs. The use of secondary beam is adopted for large span requirement.
