Abstract: The comparative analysis of the small earthquake calculation design method and the moderate earthquakecalculation design method was carried out, and the similarities and essential differences between the two design methodswere studied. Focused on the performance-based seismic design method of “two-level and two-stage” based on components,seismic ideas and design methods were elaborated, including elastic calculation of structures and bearing capacity design ofcomponents under small (or moderate) earthquake, as well as elastoplastic calculations of structures, bearing capacity anddeformation check of components under rare earthquake. The performance-based seismic design of structures based oncomponent level has been realized, which is consistent with the concept of classical theory of concrete structure based oncomponent test. Through the structural out-of-code design of a complex connected building, the quantitative evaluation ofthe deformation capacity of the normal section, the bearing capacity of the oblique section and the damage degree of thecomponents under rare earthquake was emphasized. The results show that through the performance evaluation of thecomponent under rare earthquake, structural seismic weak locations and weak members can be identified, and targetedstrengthening measures was adopted to achieve the precise optimization of the structural seismic performance, thus ensuringthe seismic safety of the structure.

Keywords:two-level and two-stage; performance-based seismic design; component hierarchy; complex connected building;quantitative evaluation
