The resistance system to the lateral force has developed with high-rise buildings. The outrigger system that is a kind of resistance system resists lateral force by setting up a big wall and trusses in a part story of building. The offset outrigger system that outrigger is horizontally moved is suggested to solve the restriction of space usage and the interception of view to the outside. In the seismic designing of buildings, the pile foundation of building piers generally have been modeled to have a fixed end in spite of Soil-Structure Interaction. And for the performance based seismic design, nonlinear static analysis is applied to seize the capacity of the structure more effectively.
To analyze the interaction effect between structures and soil, this study performed dynamic analysis and nonlinear static analysis of structures under the seismic load. This study is performed analysis of the offset outrigger system using 6 spring coefficient, considering flexibility of soil, in both conditions of sand and clay.
The results of this study were as follows; As comparing to displacement and story drift ratio, 6 spring model has the bigger value than a fixed end model because of the consideration of soil-structure interaction, otherwise the capacity of the structure of 6 links spring model was smaller than fixed end model under seismic load. And control efficiency has big values as the outrigger moved horizontally to the outside.
