Nonlinear, Incremental Structural Analysis for the Lower Miter Gate Monolith at Olmsted Locks and Dam
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 (MSA) methods as outlined in ETh 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 WES report Nonlinear, Incremental Structural Analysis of Olmsted Locks and Dam. Results of both two- and three-dimensional (2D and 3D) analyses performed on the lower miter gate monolith are presented herein. Preliminary analyses were performed using 2D models to assess effects of construction parameters prior to performing the 3D analyses. Results of 3D analyses showed that 2D analyses may not Wovide sufficient information when considering the effects of temperature.
