Abstract

The Code for Seismic Design of Buildings (GB50011-2010) in 2016 and the method of seismic performance-based design for high-rise buildings in the Guide for Performance-based Design of High-Rise Buildings (TBI2017) are compared. In view of the characteristics and limitations of the seismic performance index set by the Sino-US seismic code, a “three-index” performance index system and evaluation process considering the displacement angle of the structural interlayer, the plastic damage degree of components and the plastic strain of material is put forward; combining the example of time-history analysis of a out-of-code high-rise building under the rare earthquakes is verified. The results show that the method of seismic performance evaluation by using deformation control index in Sino-US seismic code is relatively simple; however, both are lacking in the setting of specific components and the whole structure level respectively. The "three-index" system can comprehensively and quantitatively evaluate the seismic performance of out-of-code high-rise buildings.
