ANALYSIS AND DESIGN OF BUILDING (B+G+10) WITH FLAT SLABS IN ZONE ‘II’ USING ETABS AND SAFE SOFTWARE

Abstract

Structural Engineering is a Branch of civil engineering which deals in the determination of behaviour of structures in order to predict the responses of real structures like bridges, Buildings, etc. under the improvement of expected loading and external environment during the service life of the structure. Structural Engineers these days are up against the challenging task of striving for the most efficient and most economical design with accuracy in solution while guaranteeing the final design of a building is serviceable for its design lifetime. In reality it’s very difficult to predict with certainty how much damage a building will experience for a given level of ground motion, because there are number of factors that affect the behaviour of the structural systems. The objective is to emphasize on structural behaviour of a commercial building (basement + ground+10 stories) installed with flat slabs for Bangalore (Zone 2) pertaining to medium soil. The building model is designed and analysed using ETABS (Extended Three dimensional analysis of Building System) and SAFE. ETABS is the ultimate integrated software package for the structural analysis and design of buildings. SAFE is the ultimate tool for designing concrete floor and foundation systems. The lateral loads induced from wind and earthquakes in the design and analysis of building is considered. The dead loads are calculated as per IS 875(part 1)-1987, live load is taken as per IS 875(part 2)-1987, earthquake load has been taken as per IS 1893-2002(part 1) and wind load has been taken from IS 875 (part 3)1987. The manual calculations for the design of structural members were compared with the software results which were found to be satisfactory. All the design and detailing procedures for structural members were carried out as per the guidelines of Bureau of Indian Standard code books.
