Description: Technical Report
Abstract: Miter gates at navigation locks experience loading cycles from emptying and filling of a lock's chamber as they are opened to allow traffic through the locks. Reliability analysis of miter gates at navigation locks requires definition of (a.) nonperformance modes, (b.) loads, (c.) structural strength, and (d.) methods of reliability analysis. Due to the cyclic loading nature of miter gates, the fatigue of critical details requires examination using reliability methods. The assessment of fatigue reliability of these details as a function of time requires the knowledge of strength, stress ranges, and loading cycles for these details. Prediction of loading cycles on miter gates for use in the assessment of fatigue reliability for miter gates is described. Correlation of field data for pool and tailwater elevations and barge traffic to form a loading histogram to be utilized to better predict the loading history of miter gates is explained.
