This manual provides guidance for designing reinforced concrete hydraulicstructures by the strength-design method.Scopea. This manual is written in sufficient detail to not only provide thedesigner with design procedures, but to also provide examples of theirapplication. Also, derivations of the combined flexural and axial loadequations are given to increase the designer's confidence and understanding.b. General detailing requirements are presented in Chapter 2.Chapter 3 presents strength and serviceability requirements, including loadfactors and limits on flexural reinforcement. Design equations for memberssubjected to flexural and/or axial loads (including biaxial bending) are givenin Chapter 4. Chapter 5 presents guidance for design for shear, includingprovisions for curved members and special straight members. The appendicesinclude notation, equation derivations, and examples. The examplesdemonstrate load-factor application, design of members subjected to combinedflexural and axial loads, design for shear, development of an interactiondiagram, and design of members subjected to biaxial bending.
