Uncertainties for Fixed Offshore Structures and Their Code Implications Data and model uncertainties associated with the estimation of design loads for offshore structures were analyzed. A model was developed to calculate the effect of these uncertainties on the structural reliability and recommendations were developed regarding the impact of uncertainty on design code development

A model was developed to estimate the effect of proof testing on the reliability of CANDU containment structures. The results were used to recommend proof testing requirements for future containments.

This project developed a research program to use reliability-based methods in the design, inspection and safety assessment of nuclear containment and safety-related structures. The program was based on a definition of the current needs of the industry and an assessment of how reliability methods can contribute to filling those needs.

This project was an experimental and analytical study of hull girder bending strength and local flexural torsional buckling (tripping) of stiffened plate components representative of those used in ship structures. The work included the experimental testing of twelve full-scale plate specimens in a specially constructed test frame capable of applying both in-plane and lateral loads while maintaining accurate boundary conditions. The work also included non-linear finite element analyses of various test specimens.
