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).

Soil-structure interaction is an area of major importance in geotechnical engineering and geomechanics Advanced Geotechnical Engineering: Soil-Structure Interaction using Computer and Material Models covers computer and analytical methods for a number of geotechnical problems. It introduces the main factors important to the application of computer methods and constitutive models with emphasis on the behavior of soils, rocks, interfaces, and joints, vital for reliable and accurate solutions. This book presents finite element (FE), finite difference (FD), and analytical methods and their applications by using computers, in conjunction with the use of appropriate constitutive models; they can provide realistic solutions for soil–structure problems. A part of this book is devoted to solving practical problems using hand calculations in addition to the use of computer methods. The book also introduces commercial computer codes as well as computer codes developed by the authors. Uses simplified constitutive models such as linear and nonlinear elastic for resistance-displacement response in 1-D problems Uses advanced constitutive models such as elasticplastic, continued yield plasticity and DSC for microstructural changes leading to microcracking, failure and liquefaction Delves into the FE and FD methods for problems that are idealized as two-dimensional (2-D) and three-dimensional (3-D) Covers the application for 3-D FE methods and an approximate procedure called multicomponent methods Includes the application to a number of problems such as dams , slopes, piles, retaining (reinforced earth) structures, tunnels, pavements, seepage, consolidation, involving field measurements, shake table, and centrifuge tests Discusses the effect of interface response on the behavior of geotechnical systems and liquefaction (considered as a microstructural instability) This text is useful to practitioners, students, teachers, and researchers who have backgrounds in geotechnical, structural engineering, and basic mechanics courses.
