Abstract |
The purpose of this paper is to search the optimal location of offset outrigger system in high-rise building after a structural schematic design of 80 stories building was conducted, making use of MIDAS-Gen. In this research, the key factors of analysis study were column stiffness, outrigger position in plan and outrigger location in height. For the aim of finding out the optimum position of offset outrigger system in tall building, we studied the lateral displacement in top floor which is the very essential variables in the structural design of high-rise building. The results of study showed that the column stiffness, the outrigger location in plan and outrigger location in height had an effect on the optimal position of outrigger system. Also, it is indicated that the research results can be useful in acquiring the structural design materials for seeking the optimum position of offset outrigger system in tall building.
