Abstract

This research aims to suggest an optimal location of outrigger system without upper shear wall. To achieve this objective, a schematic structure design of a 60-story high-rise building was carried out using an analysis program called MIDAS-Gen. The main analysis variables were the height ratio of shear wall to total height of building, the outrigger stiffness, and the outrigger position in height. Utilizing the analysis results, the lateral displacement distribution in top floor and the existing methods of optimal outrigger position were examined. This research proposed the optimal location of outrigger structure without upper shear wall while considering the stiffness of shear wall, the outrigger stiffness, the stiffness of exterior columns connected to the outrigger structure, the frame stiffness and the height ratio of shear wall to total height of building. Additionally, this study's results can provide significant help to gain structural engineering data when seeking a reasonable outrigger system in a high-rise building.
