Abstract: Based on an actual high-rise office building in Ganzhou City, Huichang County as an example, combined with the seismic design theory and method based on the performance, reasonably determine the performance level of the target structure and performance of each component in the fortification level according to the importance of buildings and structures and other requirements, using large-scale finite element analysis software PKPM and Midas to Building small earthquake, earthquake and earthquake elastic yield, the elastic-plastic analysis and special analysis for this project in the overrun (such as slab stress analysis, vertical stiffness analysis etc.), observe whether the obvious transfinite structure, weak layer and weak parts, take specific measures to ensure that the structure satisfies the desired performance objectives in the fortification level under the weak position.
