Performance Based Seismic Design Considering The Design Working Life Of Buildings

In this paper, the development of and research on performance-based seismic design in our contrary and overseas are summarized. According to the theory that the probabilistic distribution of seismic intensity fits Extreme Value Type HI, a method to confirm seismic power that is pertinent to the period of expectant use is discussed. At the same time, the way to deal with seismic details is given by introducing system coefficient and coefficient factor. In summary, this paper provides engineers a seismic design method that is pertinent to the period of the building's expectant use.
