Performance Evaluation of Outrigger System in Tall Buildings with Eccentric Core

The outrigger system with a core is widely used for lateral load resisting system of tall building. Recently, structural systems in tall building are adopted to eccentric core and offset outrigger or one-armed outrigger system by trends in planning buildings of irregular type. Therefore, the performance of outrigger system with eccentric core in tall building is evaluated by 50-stories examples which are analyzed for variables such as layout of core and outrigger, arm length of outrigger and depth of outrigger and belt wall.
