Abstract
The study aimed to understand the lateral behavior of vierendeel outrigger system in high-rise building. For this goal, a structure analysis and design of 60 stories building was performed by using MIDAS-Gen. And the main factors of this research were the types of outrigger system, the stiffness of outrigger and the location of outrigger system. Based on the analysis results, we analyzed and studied the lateral behavior of structure members such as slab, outrigger and exterior columns in vierendeel and general outrigger system. The study results showed that the types and the stiffness of outrigger system had an any influences on lateral behavior in vierendeel outrigger system of tall building. Also the results of analysis research can be very useful in getting the significant engineering materials for the structural design of vierendeel outrigger system in high-rise building.
