Red River U-Frame Lock Structure Analyses Comparison

摘要

This report presents a comparative investigation involving the results of the structural analyses of a simplified frame model with beam elements and a detailed plane-strain finite-element model a U-frame lock on the Red River. The GTSTRUDL computer program was utilized for this investigation. The study was scheduled on request of the US Army Engineer District, Vicksburg, and the structural dimensions and various loading cases were provided by this Corps office. To aid with the study, the District made available the program runs of the planar rigid frame model of the U-frame for these load cases. These comparisons reveal the points in each analysis that have not been considered, those that are and are not in agreement, those that may not be justified, and facts that do not appear to be correct. The importance of further investigations involving analysis of the linearly elastic U-frame structure on elastic foundation has stemmed from this study. Research into elasto-plastic foundation and dynamic soil-structure interaction effects are other related areas open for the author's expertise. (Author)
