Comparative Analysis on Wind and Seismic Behaviour of Tall Structure Building with Outrigger System

With the ongoing trend of urban densification, the development of high-rise structures has been widely adopted as a solution to limited land availability. Structural performance under lateral forces such as wind and earthquakes has been regarded as a primary concern in the design of these tall buildings. To address this, outrigger systems have been employed as an effective method to enhance lateral stiffness and control structural displacement. In recent studies, shear walls have been proposed to function as outrigger elements, offering a more integrated and efficient approach to resisting lateral loads. In this research work, it has necessary to compute the outrigger shear wall should be applied at different floor level with a view of comparative analysis of seismic and wind effects which has not been observe yet. Simulations are conducted using an analysis software to assess the response of the selected tall structure (G+79). Different models have generated and comparative analysis has conducted to show the effects of wind and seismic forces and there intensity for that, one case without outrigger and five cases of with outrigger has applied over the structure. The response of the structure to see the performance including displacement, base shear and fundamental time period of entire structure has plotted in graphs and tables to show the percentage variations both horizontal comparative analysis. Finally in conclusion, remarks for each output has inscribe with comparative observations. At last, recommendations has given based on adaptability of the outriggers applications on tall structures based on Taranath’s method.
