This popular publication is the definitive source for information on development and splicing of reinforcing bars. Now in its sixth edition, the book features data on mechanical splices including load tests for Type 1 and Type 2 splices, Grades 40 to 80. Also included are extensive tables of development and lap splice lengths for Grade 60 uncoated and epoxy-coated reinforcing bars with 3,000 to 10,000 psi concrete compressive strengths. Additionally, development and lap splice length tables for welded wire reinforcement, expanded information on headed bars, and supporting formulas for all development and lap splice tables are presented. The new edition conforms to ACI 318-14 and AASHTO LRFD Bridge Design Specifications, 2016.
