An Investigation on Structural Performance of Tall Building Embedded with Core & Outrigger System

The core and outrigger system which is mostly used in tall building, this method can be used to control the extreme drift due to horizontal load as per previous research. One more advantage by using this method is that it minimize the effect of structural harm due to horizontal loading, wind load and earthquake load also it reduce pounding effects in building. In this current work, a twenty storied RC building with and without outrigger at different position were analyzed & design. The aims of study is to find out the best position of outrigger, story drift, story displacement, stiffness, base shear and time period for outrigger corresponding to core & compare variation in displacement when outrigger is provided at different position. Also in this study we discuss efficiency of outrigger at different story height and static behaviour of RC building under horizontal loading
