Abstract— In High rise buildings, lateral loads induced by wind & earthquake are often resisted by a shear walls. But as height of building increases , the stiffness of the structure is note as more important and introduction of outrigger beams connect to the central core walls and external columns. It is provide sufficient lateral stiffness to the structure. In this paper, analysis of High rise building is carried out to find the optimizing position of outrigger system by using lateral loads. The model is analyzed in ETABS. The objective of this paper was to optimize the outrigger location. Comparing when Two , Three & Four no. of outriggers located in the structure. From the analysis, To find out result that the performance of the outrigger was efficient and three optimum position of outrigger has been found i.e. at mid height of building, second at Ht/3 and third at Ht/4 of building. In which one outrigger fixed at terrace floor.
