A Comparative Analysis of High Rise Buildings of Different Geometrical Shapes Subjected to Wind Load for RCC and Composite Structures

In today's current high-rise building construction, lateral loads such as wind loads are a key problem. Steel - Concrete Composite building, on the other hand, has acquired widespread recognition across the globe as a viable alternative to pure steel or pure concrete construction. In comparison to RCC constructions, composite structures are better suited for high-rise buildings, according to the study. They have great rigidity, stability, and strength, which may be used to withstand enormous lateral wind loads while still supporting the structure's gravity loading. In this research, ETABS 15 software was used to conduct a comparative analysis of high-rise buildings for different geometrical forms exposed to wind stress for both RCC and Composite structures. The three geometrical shapes of Rectangular, Triangular, and Plus are used with the same base plan and floor-to-floor height. All of the frames are examined first with an RCC frame and then with a Steel-Concrete Composite frame. The structure is made up of G+15 storeys. The maximum storey displacement, maximum storey shear, and maximum storey moment for both Reinforced Concrete and Steel-Concrete Composite structures were calculated using ETABS 15 software, and comparisons were made for all three geometrical shapes to see which has the most stability and resistance to wind load among all the cases considered.
