COMPARISON OF PERCENTAGE STEEL AND CONCRETE QUANTITIES OF A R.C BUILDING IN DIFFERENT SEISMIC ZONES

Abstract

One of the devastating hazards on the earth is earthquake, which causes damage to all forms of life. It is impossible to stop earthquake but loss or damage to the structure can be minimized through proper design and detailing. The main objectives of present study were to study the performance and variation in steel percentage and quantities concrete in R.C framed irregular building in gravity load and different seismic zones. And to know the comparison of steel reinforcement percentage and quantities of concrete when the building is designed as per IS 456:2000 for gravity loads and when the building is designed as per IS 1893(Part 1):2002for earthquake forces in different seismic zones. In this present study five (G+4) models were considered. All the four models were modeled and analyzed for gravity loads and earthquake forces in different seismic zones. ETABS software was used for the analysis of the models. After analysis the results of support reactions, volume of concrete and weight of steel reinforcement in footings, steel reinforcement percentage in beams and columns were tabulated.
