This book comprises most of the papers presented at the First US/Japan Workshop on Life-Cycle Cost Analysis and Design of Civil Infrastructure Systems, held in Honolulu, Hawaii, August 7-8, 2000, and several invited contributions, mostly from Europe. The 18 papers cover a wide range of studies on life-cycle cost analysis, design, maintenance and management of civil infrastructure systems. Contributions are from a range of internationally recognized researchers and practicing structural engineers from the United States, Japan, and Europe. Topics include: conceptual design of structural systems; time-variant reliability of structures; structural health monitoring and symptom-based reliability; monitoring and testing for fatigue prediction; lifetime reliability profiles for fatigue and corrosion; maintenance planning for road pavements and structures; maintenance planning of reinforced concrete decks; bridge management systems; optimized and conventional bridges; optimal planning of maintenance and inspection; life-cycle cost assessment for bridge maintenance; specifications to aid life-cycle cost analyses; maintenance cost of deteriorating civil infrastructures; probabilistic models of cost for management of existing structures; and user cost and its applications to bridge management systems. This book will be invaluable to all concerned with life-cycle costing of civil infrastructure systems.
