Abstract:

In modern tall buildings, lateral loads induced by wind or earthquake are often resisted by a system of coupled shear walls. But when the building increases in height, the stiffness of the structure becomes more important and introduction of outrigger beams between the shear walls and external columns is often used to provide sufficient lateral stiffness to the structure. In this paper, analysis of tall building was carried out to find the optimum position of outrigger system by using lateral loads. The three dimensional model using ETABS was considered. The objective of this paper was to study the outrigger location optimization and the efficiency of each outrigger when three outriggers are used in the structure. From the analysis, result has been found that performance of the outrigger was efficient and three optimum position of outrigger has been found i.e. at mid height of building, second at 3/4th of height and third at 1/4th of height of building.
