The theory of performance-based seismic design is a new concept in the world in 1990s. It is a revolution of the current seismic design procedures. In this paper, the background of its occur rence, the development, the basic idea, the main properties and the present research are summarized. Its importance to improving the seismic design theory is pointed out finally.
