Comparative Study on Dynamic Performance of Multistoried RCC Building Frames with Flat Slab and Grid Slab

Modern slab systems have showed potentials for improvement in the conventional techniques of slab casting. Recent advances in the field of RCC Design are linked to the use of Flat Slabs and Grid Floors. Flat Slabs are highly versatile elements widely used in construction, providing minimum depth, fast construction and allowing flexible column grids. In flat slabs, the beams used in conventional slabs are done away and the slab is made to rest directly over the columns. In case of higher loads, a drop panel or a column head is provided to reduce the intensity of loads. Flat slabs are particularly appropriate for areas where tops of partitions need to be sealed to the slab soffit for acoustic or fire reasons. Grid floor systems consist of beams spaced at regular intervals in perpendicular directions, monolithic with slab. The rectangular or square void formed in the ceiling is advantageously utilized for concealed architectural lighting. They are generally employed for architectural reasons for large rooms such as auditoriums, vestibules, theatre halls, show rooms of shops where column free space is often the main requirement. This paper focuses on studying the behavior of conventional slab, flat slab and grid slab separately. The object of the present work is to compare the behavior of multi-storey buildings having Conventional slab, flat slabs with drops and grid slab system with shear wall under the effect of dynamic loading using SAP software by framing the models of flat and grid slab.
