Changes made to the development length provisions to consider confinem
ent effects are examined. The reasons why bars with small cover and wi
th close spacing require longer development and splice lengths are pre
sented. The elimination of the Class C splice is also addressed. Chang
es in the top bar effect and the introduction of factors for epoxy-coa
ted reinforcing bars are discussed. Sample problems illustrate usage o
f the new provisions.
