A Comparative Study on High Rise Building for various Geometrical Shapes Subjected to Wind Load of RCC & Composite Structure using ETABS

In today’s modern construction of high rise buildings, lateral loads such as wind load is of major concern. However Steel – Concrete Composite construction has gained wide acceptance worldwide as an alternative to pure steel or pure concrete construction. The review shows that, the composite structures are best suited for high rise buildings compared to that of RCC structures. They offer high stiffness, stability and strength which can be utilized to resist large lateral wind loads and simultaneously support the gravity loading of the structure. In this project, a comparative study has been carried using ETABS 15 software on high rise building for various geometrical shapes subjected to wind load for both RCC and Composite structure. The three geometrical shape of Rectangular, Triangular and a Plus shape are taken with each of similar base plan and same floor to floor height. All the frames are analyzed firstly using RCC frame and then Steel – Concrete Composite frame. The building frame is comprised of G+15 storey. By the analysis done using ETABS 15 software the values such as maximum storey displacement, maximum storey shear and maximum storey moment for both Reinforced Concrete and Steel – Concrete Composite structure and comparison has been done for all three geometrical shapes to compare which has more stability and resistance against wind load among all the cases considered.
