Reynolds BEng 24th June 2026 1. Risk Assessment Context Nuclear containment structures rely on reinforced concrete cylindrical shells where long-term performance depends on composite action between steel reinforcement, concrete, and internal cement-aggregate bond. Current design guidance uses empirical coefficient tables whose original theoretical provenance (Viktor Lewe 1915 thin-shell matrix theory) is not clearly referenced. This … Continue reading PhDd.
