本文介绍了钢筋混凝土构件抗剪设计的桁架模型方法和相关理论。阐述了深梁、牛腿和其他非标准结构构件设计的现实模型，讨论了结构混凝土抗剪设计的背景理论和多种不同方法的互补性。这些相对较新的程序为混合荷载效应的结构混凝土配比提供了统一、易懂和安全的设计框架。

Truss model approaches and related theories for design of reinforced concrete members to resist shear are presented in this document. Realistic models for design of deep beams, corbels, and other nonstandard structural members are illustrated and background theories and the complementary nature of a number of different approaches for the shear design of structural concrete are discussed. These relatively new procedures provide a unified, intelligible, and safe design framework for proportioning structural concrete for combined load effects.
