- single source of information on structural assessment techniques for marine and land-based structures
- examines the residual strength and reliability of aged structures
- assesses current practices covering inspection, health monitoring and maintenance
Any structural system in service is subject to age-related deterioration, leading to potential concerns regarding maintenance, health & safety, environmental and economic implications. Condition assessment of aged structures is an invaluable, single source of information on structural assessment techniques for marine and land-based structures such as ships, offshore installations, industrial plant and buildings. Topics covered include:
- Current practices and standards for structural condition assessment
- Fundamental mechanisms and advanced mathematical methods for predicting structural deterioration
- Residual strength assessment of deteriorated structures
- Inspection and maintenance of aged structures
- Reliability and risk assessment of aged structures
Professionals from a broad range of disciplines will be able to gain a better understanding of current practices and standards for structural condition assessment or health monitoring, and what future trends might be.
