摘要

The current structure seismic design method is force-based, and played an important role in buildingseismic design. But it does have some shortcomings. The theory of performance-based seismic design(PBSD) was suggested firstly by the American scientists and engineers in the beginning of 1990s. TheJapanese and European scholars in earthquake engineering field took great interest in it and devoted to itat all of the standpoints. The PBSD theory stemmed from displacement-based seismic design(DBSD)which is supposed by Moehle [4] in Berkley University in California. It is based on the structure analysisand is a revolution in development of seismic theory. It includes all aspects of design and has importantmeanings. The background of the occurrence, the development, the basic idea, the main properties of thetheory and the present research are summarized in this paper. Its importance to improve the seismic designtheory is pointed out, too, finally.
