ABSTRACT
ABSTRACT: In Japan, the Specifications for highway bridges have been revised from specification-based design to performance-based approach in order to accommodate smart structures. As one of the important revision tasks, there is a consideration of limit states and performance at limit states during and after hazards. However, there has not been sufficient attention to limitstates of smart structures. As main revision tasks for performance-based design, we consider the manifestation of limit sates and required performance levels, the proposition of methods for guaranteeing safety of each structure, and the planning for evacuation for disaster. In this study, a new concept is proposed for design and maintenance following hazards in performance-based design system. This concept is named as live design and live management. Two concepts such as conventional maintenance concept and live design concept in emergency are fused into a new maintenance management concept of highway bridges in performance-based design system.
