Abstract
The research intended to understand the lateral behavior in core and offset outrigger system. To achieve this goal, a structural analysis and design of 70 stories building was carried out by making use of MIDAS-Gen. And the primary parameters of this analysis were the stiffness of outrigger and the location of outrigger in plan. On the basis of the analysis results, we analyzed the lateral behavior of structural elements such as slab, outrigger and exterior columns in core and offset outrigger. In this analysis research, it is indicated that the stiffness of outrigger and the outrigger location in plan had an any impact on lateral behavior in outrigger system of tall building. Specially, slab stresses in core outrigger system were highly distributed in the slab near the outrigger system to connect shear walls and exterior columns while slab stresses in offset outrigger system were highly distributed in the slab between the outrigger system and shear walls. Also the study results can be of significant help to obtaining the engineering data for the reasonable structure design of the high-rise outrigger system.
