Resolutions:

1. The International Workshop on Performance-Based Seismic Design - Concepts and Implementation was held in Bled, Slovenia, 28. June – 1. July, 2004. The main sponsors of the Workshop were the U.S. Pacific Earthquake Engineering Research Center and the Ministry of Education, Science and Sport of the Republic of Slovenia. Workshop attendees included representatives from 14 countries from Asia, Europe, and North and South America.
2. The Workshop provided a valuable forum to exchange research results and design practice ideas on issues important for seismic risk reduction and the development of performance-based earthquake engineering concepts. The theme of the workshop was to assess the state of knowledge and practice related to performance-based design and its implementation, and to identify challenges that need to be addressed so that progress in research and in the implementation in engineering practice can be accelerated and a common foundation can be established on which to base the various approaches advocated in different countries.
3. The participants agreed that the Workshop has led to a greater understanding of many of the issues involved in performance-based design and that much progress has been made in the development of concepts and procedures suitable for implementation in engineering practice. Nevertheless, many issues remain unresolved and additional research and studies are needed to implement rigorous performance-based design with confidence.
4. The participants agreed that performance-based design concepts provide a suitable framework for future seismic code development.
5. The workshop participants recognize that common interests exist among researchers and practitioners of the countries represented at the Workshop. Progress in research and in the implementation in engineering practice can be accelerated by the international dialog on the worldwide implementation of new ideas. Cooperative research on issues of common interest should be encouraged. The participants recognize that performance-based design has many facets and may take on very different meaning and approaches depending on prevailing economic and societal priorities. Nevertheless, by continuing the international dialogue, a common foundation can be established on which the various approaches advocated in different countries can be based.
6. The participants see an urgent need for worldwide sharing of data obtained from experimental and analytical studies and from field measurements taken during earthquakes. A protocol for international data sharing should be developed and efforts should be initiated for the creation of a worldwide data repository.
7. In order to accelerate the transfer of knowledge from researchers to engineering practice, the workshop participants see a need for incorporating performance-based design concepts and reliability theory into educational curricula.
8. Recognizing the benefits of the exchange of ideas that occurred at the workshop, the participants agreed that international gatherings to share information on the development of performance-based design should be held on a periodic basis.
