Three-Dimensional, Nonlinear, Incremental Structural Analysis of a Culvert Valve Monolith Wall, Olmsted Locks.
Abstract
The Olmsted Locks and Dam will be constructed on the Ohio River at mile 964.4 and will replace two existing locks. Extensive investigations have been undertaken to determine the constructability of the lock using nonlinear, incremental structural analysis (NISA) methods as outlined in ETL 1110-2-324, "Special Design Provisions for Massive Concrete Structures." The need for the comprehensive studies was a result of the fact that the Olmsted Locks will be constructed using the unprecedented w-frame type construction. This report is a part of the third phase of the study for evaluation of the constructability of the Olmsted Locks. The first two phases evaluated parameters such as creep, shrinkage, plane stress, plane strain, placing schemes, and concrete mixtures, and results are reported in a U.S. Army Engineer Waterways Experiment Station report entitled "Nonlinear, Incremental Structural Analysis of Olmsted Locks and Dam." Results of two analyses performed on a wall portion of a culvert valve monolith are presented in this report. The analyses were three dimensional. The first analysis was performed based on proposed construction parameters and the second analysis was performed to evaluate changes to those parameters in an effort to reduce cracking that was predicted in the first analysis.
