- Abstract
- This workshop was held to summarize the current state of knowledge and to establish research needs on seismic aspects of highway bridge design. Main objects included the following: (1) to evaluate current knowledge and practice in the planning, design, and construction of earthquake-resistant bridges; (2) to examine needs and priorities for immediate and long-range research required to minimize gaps in current knowledge and improve current practice; and (3) to improve cummunication and cooperation between research and professional organizations as well as among different research groups. Forty-seven specialists from professional and research disciplines participated in workshop activities. Recommendations formulated during the workshop included the need for greater cooperation and communication between researcher and professionals, evaluation and dissemination of available data and pertinent design-oriented technical information, an on-going program motion research to review and upgrade seismological and geological bases of design, a program of integrated and experimental research on the three-dimensional linear elastic and hysteric behavior of real bridges under seismic loading conditions, and the development of procedures to determine the seismic loading conditions, and the development of procedures to determine the seismic resistance and acceptable damage loads of existing bridges. Appendices list program participants, members of working groups, and research publications.
