Abstract: In this project, the height of building is 149.6m, falling into a B-class high-rise building, and a frame-core tube structure is chosen. Based on the seismic performance of the design requirements, an elastic-plastic time history of analysis of the overall model was performed by the programs of SAUSAGE under the rare earthquake, and the distribution law were obtained in some of major indicators including displacement angle and shear between the structural layer, the damage of concrete members. In addition, detailed supplementary analyses were performed for some special members, such as the floor slab with large opening and columns beyond several floors. According to the result of analysis, some strengthening measures were taken for the weak regions and the structural overall expected performance can satisfy the requirement of D-level performance goal.
