Comparative Study on Wind Analysis of Multi-story RCC and Composite Structure for Different Plan Configuration

Abstract

The multi story high rise RCC structures are more bulky and less ductile in nature as compare to composite structures. This study investigates the comparison between RCC and composite structure under the effect of wind, additional to it composite structure also includes different plan configurations. In this study total fifteen number of building model are prepared and analysis for wind load by using ETABS 2015. The wind analysis is performed for different heights such 20m, 50m and 80m. In addition, the comparative study concludes that the composite structure are larger ductile in nature and more susceptible as compare to RCC structure and the composite option is better than RCC for multi story buildings. In addition, the comparison of different plan configuration shows that the response of parameter such as story displacement, story stiffness, base reaction and time period under effect of wind. The purpose of this analysis is to determine the most effective shape of structure in prone zone.
