Strength Design of Reinforced Concrete Hydraulic Structures. Report 4. Load-Moment Characteristics of Reinforced Concrete Circular Conduits
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.
