Gerstle and published by . This book was released on 1988 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various analytical and experimental aspects of the US Army Engineer Waterways Experiment Station concrete pipe test program were studied in an effort to maximize the returns from this project. Methods of flexural strength prediction, based on both elastic and plastic approaches, are presented and applied to the test specimens. Different approaches to determination of flexural strength are critically discussed, and the applicability of each approach is checked by comparison with test results. Graphical longhand design methods and uses are presented and explained by examples. These approaches are intended to provide the basis for future computerized design tools. The shear strength of concrete rings under various loading conditions is explored, using several available methods. Since these methods seem unable to predict the shear strength of rings under distributed loads, the need for further study along these lines might be helpful. However, the apparent fact that shear will not be critical in concrete pipe in the ground may deem this in fact a nonproblem. Further necessary research directions for optimal design of concrete pipe are noted. (FR).

This book was released on 1989 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: A strength design (SD) procedure for buried reinforced concrete circular conduits is presented. The procedure is a combination of results produced through recent work sponsored by the Corps of Engineers and recent studies sponsored by the American Concrete Pipe Association. The SD procedure accounts for both flexure and shear in buried circular conduits subjected to the uniform loading conditions of Engineer Manual 1110-2-2902. Expressions are included that account for the effects of concrete compressive strength and radial tension. A criterion for limiting the flexural reinforcement ration to prevent unacceptable crack width is also included. This organized presentation of the procedure will enable designers to evaluate further the application of recent research to real problems, with the goal of improving the Corps' SD methods. Keywords: Hydraulic structures.

Gerstle and published by . This book was released on 1987 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of tests of model reinforced-concrete rings simulating culvert sections under radial loads was carried out at WES. These tests are described in Report 5 of this series. The purpose of this study was to perform nonlinear finite element analyses of these models, to compare analytical results with test results, and to produce a realistic strength design methodology for these structures.

Chiarito and published by . This book was released on 1986 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of initial curvature on the trust-moment characteristics of reinforced concrete circular conduit sections was investigated. This study was undertaken since conduit sections built by the Corps of Engineers are often so sharply curved relative to their thicknesses that initial curvature effects might be significant. The effect of initial curvature was investigated through curved beam, Airy stress function, and nonlinear finite element analyses. In addition, three model conduits representative of Corps construction were instrumented and simultaneously loaded on eight equally spaced diameters. For the range of design variables investigated, the analytical and experimental results indicate that initial curvature has no statistical significant effects. Further testing will be needed to obtain a larger statistical sample and evaluate the effects of more extreme curvatures than studied in this report.

This book was released on 1993 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strength Design for Reinforced-Concrete Hydraulic Structures is written in sufficient detail to not only provide the designer with design procedures, but also to present examples of their application. A review of general detailing requirements, as well as strength and serviceability requirements, create a strong understanding of the strength-design method. Latter chapters feature examples that demonstrate load-factor application, the design of members subjected to combined flexural and axial loads, the design of members subjected to biaxial bending, and the design for shear strength, including provisions for both special straight and curved members.

Wright and published by . This book was released on 1987 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: A test program was initiated to investigate the two-dimensional failure response of reinforced concrete (R/C) circular conduits under a known 16-point loading. This was achieved by testing 18 R/C models to failure. The test specimens were instrumented to obtain concrete and steel strains and intrados deflections at the crown and springing line. Steel percentage ratios, loading distribution, and curvature were varied for each test. All models failed primarily in flexure; ductile and brittle failure modes were observed. In a later test program, models which were exposed to 2-point and 4-point loadings and the three-edge-bearing method failed in diagonal or radial tension.

Available in PDF, EPUB and Kindle. Book excerpt: This report presents design aids for use in the design and analysis of reinforced concrete hydraulic structural members subjected to combined uniaxial bending and axial loads. A total of 190 load-moment strength interaction diagrams for both single and double reinforced members with various compressive strengths of concrete, yield strengths of steel reinforcement, reinforcement ratios, and concrete covers is included. In addition to design aids, this report includes a commentary explaining how each design aid was calculated, and design examples illustrating the use of the design aids. (Author).
