Abstract: Grid slab frame systems consisting of beams spaced at regular intervals in perpendicular directions, monolithic with slab. Generally they are used for architectural reasons for large rooms for example: auditoriums, vestibules, theatre halls, showrooms of shops where column free space is often the main requirement. A rectangular or square void formed in the ceiling is advantageously utilized for concealed architectural lighting. This paper describe the study of analysis of Grid slab frame for seismic forces and compared with Conventional R.C. frame. The different parameter are studied displacement, storey drift, base shear and moments on the column. For analysis ETAB software is used. Keywords: Grid slab, ETABS, Seismic forces.
1. INTRODUCTION Inter-connected grid systems are being commonly used for supporting building floors bridge decks and overhead water tanks slabs. A grid is a planar structural system composed of continuous members that either intersect or cross each other. Grids are used to cover large column free areas and have been constructed in number of areas in India and abroad. Is subjected to loads applied normally to its plane, the structure is referred as Grid. Which is composed of continuous member that either intersect or cross each other. Grids in addition to their aesthetically pleasing appearance provide a number of advantages over the other types of roofing systems. 1.1 Advantages of Grid slabs: 1. Grid slabs are used for larger span slabs or floors and used when there is limited requirement for number of columns. 2. The load carrying capacity of Grid slab is greater than the other types of slabs. 3. They provide good structural stability along with aesthetic appearance. Hence, it is constructed for airports, hospitals, temples, churches etc. 4. The Grid slab can be made of concrete or wood or steel among those concrete waffle slab is preferred for commercial buildings and remaining two are preferred for garages, decorative halls etc. 5. It has good vibration control capacity because of two directional reinforcement. So, it is useful for public buildings to control vibrations created by movements of crowd. 6. Grid slabs are lightweight and requires less amount of concrete, hence it is economical. 7. Concrete and steel volume required is small, hence, light framework is enough for waffle slab. 8. Several services like lighting, plumbing pipes, electrical wiring, air conditioning, insulation materials etc. 9. Can be provided within the depth of waffle slab by providing holes in the waffle bottom surface. This system is called as Holedeck.
