Abstract： The performance-based seismic design method is an internationally advanced technology， which is applicable to the structural design of complex and out-of-gauge high-rise buildings. The code of China adopts the basic objective of seismic fortification of "unbreakable by small earthquake， repairable by moderate earthquake and not collapsed by large earthquake". The performance objective required by the code of China can be achieved through seismic design of out of gauge high-rise structures. Taking a complex super high-rise project in Chongqing as an example， this paper introduces the process of performance-based design of the structure.

Keywords： performance design; out-of-gauge high-rise building; elastoplastic; time-history analysis; SAUSAGE
