Abstract
The development of a generalized framework for assessing bridge life-cycle performance and cost, with emphasis on analysis, prediction, optimization, and decision making under uncertainty, is briefly addressed. The central issue underlying the importance of the life-cycle approach to bridge engineering is the need for a rational basis for making informed decisions regarding design, construction, inspection, monitoring, maintenance, repair, rehabilitation, replacement, and management of bridges under uncertainty by using multi-objective optimization in order to balance conflicting criteria such as performance and cost. A number of significant developments are summarized, including time-variant reliability, risk, resilience, and sustainability of bridges and bridge transportation networks. Furthermore, the effects of climate change on the probabilistic life-cycle performance assessment of highway bridges are addressed. Moreover, integration of SHM and updating in bridge management and probabilistic life-cycle optimization considering multi-attribute utility and risk attitudes are presented.
