| Description: | Technical Report Abstract: The Olmsted Locks and Dam will be constructed on the Ohio River at mile 964.4. Since the design of the locks is the unprecedented w-frame type structure, extensive studies have been undertaken to determine the constructability of the lock. This report is part of the third phase of a study evaluating the constructability of the Olmsted locks using nonlinear, incremental structural analysis methods outlined in ETL 1110-2-324, "Special Design Provisions for Massive Concrete Structures." The first two phases of the study, which led to the third phase, evaluated parameters such as plane stress versus plane strain analysis, creep, shrinkage, placing schemes, and two concrete mixtures and are reported in aWES report "Nonlinear, Incremental Structural Analysis of Olmsted Locks and Dams." Contained in this third phase report are results of parametric studies on insulation, placing temperatures, placement intervals, various ambient conditions, and different concrete set times. Results of analyses performed led to recommending higher placing temperatures than originally planned and shorter insulation periods for portions of a chamber monolith. NOTE: This file is large.
