Abstract : The Olmsted Locks and Dam will be located on the Ohio River and the locks will be a W-frame type of structure, which is currently unprecedented within the Corps of Engineers. Because of this fact and due to the high fly ash concrete mixture planned for the project, and extensive nonlinear, incremental structural analysis (NISA) was performed. Parameters evaluated included two different placing schemes, plane stress and plane strain analyses, two different concrete mixtures, creep, and shrinkage. The report contains two phases. In the first phase, parameters such as plane stress and plane strain, block and strip placement schemes, and mixtures 6 and 11 were evaluated. The second phase included performance of several analyses based on the load case combinations contained in ETL 1110-2-324, 'Special Design Provisions for Massive Concrete Structures', and included evaluation of the effects of creep and shrinkage. The second phase results were also used to validate the analyses performed in the first phase
