Understanding engineering structural health is vital for making informative decisions in maintaining and renewing infrastructure to meet increasing demands. The two volumes of Infrastructure Health in Civil Engineering discuss the importance of linking the decision-making concept to damage identification and structural modeling. It examines the process of addressing and maintaining structural health, including measurements, structural identification, and damage identification. It also discusses the theoretical and practical issues involved for each aspect. Emphasizing state-of-the-art practice as well as future directions, this text also features numerous practical case studies and covers the latest techniques in sensing and sensor utilization.
