Abstract
This study purposed to investigate the optimal outrigger location in tall building with cap truss after a structural schematic design of 80 stories building was performed by using MIDAS-Gen. In this paper, the main parameters of structural analysis were the outrigger location and stiffness of main structural elements (outrigger, exterior column, shear wall etc). In order to search the optimal outrigger position in high-rise building with cap truss, we analysed and examined the lateral displacement of top floor which is one of the very important considering factors of tall building structural design. The paper results indicated that the outrigger location and the stiffness of main structural elements such as outrigger, exterior column and shear wall had an effect on the optimal outrigger location. And it is verified that the study results provided the basic engineering data for fixing the most optimal outrigger location for minimizing the lateral displacement of tall building.
