Splices and Details of Reinforcement

Abstract

Structurally sound details and proper arrangements of reinforcing bars are vital to the satisfactory performance of reinforced concrete members and structures. Concurrently, such details and bar arrangements should be practical and buildable, as well as cost-effective. Hence details, development, and splices of reinforcement—the topics of this chapter—are a crucial aspect of the design process. Of the ten more important items of information that must be included in the design drawings, typical details, or project specifications, two of the items cover development and splices of reinforcement (Sections 1.2.1-h and 1.2.1-i, and Commentary R1.2.1). These items are anchorage (embedment) length of reinforcement and location and length of lap splices; and the type and location of mechanical and welded splices. Code Chapter 12 also states: splices of reinforcement shall be made only as required or permitted on design drawings, or in project specifications, or as authorized by the engineer (Section 12.14.1).
