Abstract

In India reinforced concrete structures are mostly used since this is the most convenient and economic system for low-rise buildings. However, for medium to high-rise buildings this type of structure is no longer economic because of increased dead load, less stiffness, span restriction and hazardous formwork. So the Structural engineers are facing the challenge of striving for the most efficient and economical design solution. Composite construction combines the better properties of both steel and concrete along with lesser cost, speedy construction, fire protection etc. The major objective of this project work is to study the seismic behaviour of high rise building made by reinforced cement concrete, steel and composite material. In this work multi-storied commercial building (G+14) located in
seismic zone IV is considered. The equivalent static method and push over analysis is adopted and analysis is carried out by using ETABS V15 software. The various seismic parameters such as storey shear, displacement, storey drift, base shear and time period are obtained from analysis and the results were compared. From the study it is observed that Storey displacement, Storey shear, Storey drift, time period, Bending moment and shear force are reduced in steel and composite building as compared to R.C.C building. These values are slightly more in case of composite building as compared to steel building. From the pushover analysis it is clear that composite building has higher values of displacement and base shear as compared to R.C.C and steel building. From overall study it is concluded that the composite building frame shows better performance due to seismic effect as compared to R.C.C building frame, and steel building frame
