Comparative Study Of Conventional Slab And Grid Slab Using Etabs In Earthquake Zoning In India

Abstract

The rapid growth of the urban population and the consequent pressure on limited space has considerably influenced multi-storied building construction. With increase in demand for space, construction of multi-storied buildings is becoming a necessary part of our living style. These multi-storied buildings can be constructed using various structural systems. Two main groups according to the arrangement of slabs, beams or girders, and columns are Framed Structure and flat slab structure. Framed structures are the structure having the combination of beams, columns and slabs to resist the lateral and gravity load. These structures are usually used to overcome the large moments developing due to the applied loading. Grid slab consists of beams spaced at regular intervals in
perpendicular directions which are monolithic with slab. These slabs are generally used for architectural purpose for large spans such as public assembly halls, auditoriums; show rooms were the slab has to cover a large column free space is required. Since gird slab offers more stiffness the rectangular voided pattern is used in present. In this project, we are going to compare the structural behaviour of both grid slab and conventional slab in multi-storied building. This multi-storied building structure will be analysed not only considering the vertical loads (dead load & live load), it also includes lateral load (earthquake load). Earth quake loads will be considered for all different zones in India. Structural modelling & analysis will be done using ETABS software
