Wind Analysis of Tall Building Consists of Different Framing Systems over the Height

In the present days, reinforced concrete and steel structures are mostly used since, these two have been the most convenient and economic system for a low rise buildings. However, for a medium to high rise buildings this kind of structures are hazardous and is no longer economic due to reduced stiffness, increase in dead load and span limitation. So it has been a challenging task for the structural engineers in striving for the most economic and effective design solution. So the composite material usage is of particular interest, due to its capability in improving the overall performance of structure. In India, many structural engineers are unwilling to accept the usage of composite steel-concrete structure because of complication in its analysis and design. But the literature describes that with proper configuration, the composite system can afford an exceptionally effective structural system with high strength and better wind performance characteristics. The present study discusses the wind response of regular and vertical irregular tall building by using different framing systems over the height of the building. So, among all these frame types concrete will be the better option but in addition to this we have an another option that is the Combined model which is preferable in places where the wind response is more on buildings. So to optimize this wind response, a Combined model of RCC, Steel and Composite frames as combination has been developed and is analyzed using ETABS software, and there by the combined model has proven to be the better option.
