Abstract
A pilot study regarding the design and development of a Structural risk assessment Program (STRAP) for the structural maintenance of Canadian naval vessels is presented. First, the technical considerations pertaining to the development of a state-of-the-art, user-friendly, and fully-integrated structural damage evaluation tool are extensively discussed. The concept of a workstation computer-based STRAP system is then defined. Specific recommendations for the work required for the computational tool and the associated data gathering activities to support the operation of the program are given. This includes details of costs, time schedules and risk levels associated with the development effort. Suggestions of strategies and specific work items for verification and validation of the STRAP package both at the module and overall program level are offered. Recommendations on some important research issues, especially relating to residual and restraint strains/stresses and their effects on fatigue and fracture are given. The fesibility of the STRAP concept is demonstrated within the framework of the finite element method and with reference to both deterministic and probabilistic approaches. The demonstration is performed on a workstation HP 720 using a pilot program developed during the course of the project. TRUNCATED.
