Concrete Growth and Fatigue Analysis of Chickamauga Lock Miter Gate Anchorages
Abstract
Severe cracking has been observed on the miter gate anchorages at Chickamauga Lock, Nashville District, U.S. Army Corps of Engineers. A structural analysis of these anchorages was conducted to determine how much longer they could remain in service before failure is expected. This analysis included a review of existing structural analysis reports, estimates and prediction of observed concrete growth in the area near the anchorages, and fatigue life estimates. The fatigue life estimates included the concrete growth estimates and also included the stresses and strains taken from measurements recorded during miter gate movements during lockages. The results of this analysis are discussed as well as possible ways to extend the life of the existing anchorages and considerations for if and when the anchorages are replaced.
