Taking appropriate timely actions requires good understanding of the infrastructure-its current and expected condition in the future. This book addresses practical applications, including retrofitting and rehabilitation due to earthquake damage, corrosion, and fatigue. It covers management and maintenance of different types of structures using prestressed and reinforced concrete, and fiber reinforced polymers (FRPs). It also examines the use of sensors in damage detection and load testing. The authors also stress the importance of integrating decision making or cost benefit ideas into all tasks to the success of a project.
