In-service structural systems are subject to age-related deterioration, leading to concerns regarding maintenance, health and safety, environment and economics. This book provides a single source of information on structural assessment techniques for marine and land-based structures and offers professionals from a broad range of disciplines a better understanding of current practice, how to apply the latest advanced design and development technologies in condition assessment, and likely future trends. Chapters are grouped in five broad themes: current practices and standards for structural condition assessment; fundamental mechanisms and advanced mathematical methods for predicting structural deterioration; residual strength assessment of deteriorated structures; reliability of aged structures; and survey, inspection and maintenance.
