Abstract
Structural engineers are facing the challenge of most efficient and economical design with accuracy in answer whereas ensuring that the ultimate design of a building should be safe and serviceable over its life – time. Nowadays, structural needs for high rise buildings are changing and expansion of planning is becoming more significant. In the present work, comparative study of purely reinforced cement concrete, purely steel and lower floors of reinforced cement concrete with above floors of steel (G+7) residential building which is situated in earthquake zone-III for earthquake loading and wind zone V for wind loading to achieve different use in height direction and great public atrium in lower stories that provides attractive free space. ETABS is incorporated with all the main analysis engines that's static, dynamic, Linear and non-linear, etc. This software is used to analyze and design of buildings. Taking the horizontal loading effects of wind & seismic forces are according to IS 1893:2000 (part 1) and IS 875(part 3), linear static analysis and response
spectrum analysis are performed using ETABS 2014. Comparison of steel building over reinforced cement concrete building, purely steel building and purely reinforced cement concrete building is made by considering story displacement, story drift, story shear, story stiffness, time period of seismic response and wind response and it is found that hybrid structure is found to be more economical where horizontal expansion is restricted.
