    Super high rise building has become an important structure type in urban development, and the seismic performance of the complex out of code high rise structure system is currently a critical concern. The actual project of an international trade center in a city was taken as an example in this paper, and a finite element model of the complex super high rise structure was established through the performance based seismic analysis and calculation platform OpenSees. The reliability of the model was verified by the identification of dynamic parameters based on the in seismic analysis vibration detection technique. Dynamic response analysis of the structure under earthquake was then carried out, taking into consideration the base shear force, story drift ratio, displacement of structure top, and structural damage. The research results can provide technical support for the seismic design of complex super high rise building structures.
