Abstract: The business building analyzed in this paper is located in the middle Bank of Huangpu river and complicated out-of-codes SRC frame-core structural system is used in this structure. The overall structural system and foundation design were introduced firstly, and the seismic analysis and performance-based design were also mainly introduced. According to the research on seismic performance, the methods of solving the problems of out-of-codes structures were proposed and principles and goals of performance-based design were studied. The overall calculation of frequent and intermediate earthquake and the static elastic-plastic ultimate seismic analysis under rare earthquake were carried out. The results showed that the objective of performance-based design is reasonable for this project and the safety of the structure can be ensured.

Keywords: out-of-codes composite structure; structural system; performance-based seismic design; elastic-plastic dynamic analysis
