The resistance system to the lateral force has developed with high-rise buildings. The tube structure is one of the most effective lateral resisting structure system that behaves like cantilever basically.
This study adopts response spectrum analysis and push over analysis to evaluate the seismic performance of the tube structures. To analyze the effect between tube structures and soil types, this study performed capacity spectrum method(CSM) under the seismic load. A intersection point of capacity curve and demand curve is performance point. In this paper, after searching for performance point according to return period, performance level is evaluated.
