The exterior walls of arctic oil and gas production structures will be subject to large, concentrated ice forces. Composite steel/concrete walls have been proposed as a cost-effective solution to resisting these forces. The research discussed in this paper has investigated the behavior and failure mechanisms of composite walls, so that recommendations can be made concerning analysis and design methods and effective construction details. The research involved the development of design-oriented ultimate strength models, as well as the physical testing of composite wall specimens. Results are presented in this paper for tests on composite beam and composite slab specimens. The high strength and great ductility of this form of construction is demonstrated. Effective design methods utilizing empirical design equations and limit analysis plasticity solutions are given.
