This report reviews the present (1973) state-of-the-art in the knowledge of the shear strength and behavior of reinforced and prestressed concrete beams, deep beams, brackets, and other members. Although design criteria are discussed, specific design recommendations have not been made in this report. Chapter 1 introduces the report and briefly reviews the more important types of shear failures. Chapter 2 discusses the basic mechanisms of shear transfer in reinforced concrete members. Chapter 3 deals with beams. The first half of this chapter describes the behavior and strength of beams failing in shear.
