Calculate the required embedment length of the deformed bars inthe following four cases:
(a) No. 7 bars (22.2-mm diameter), top reinforcement in singlelayer in a beam with No. 3 stirrups. Given:
fy = 60,000 psi (414 MPa)
f ’c =4000 psi (27.6 MPa), normal weight concrete
clear spacing between bars =2db
clear sidecover = 1.5 in. on each side
bars not spliced
(b) Same as part (a) except that clear spacing between bars =db or 1-in. minimum. The bars are epoxycoated.
(c) Same as part (a) except that clear spacing between bars =3db and the bars are not top bars.
(d) Assume that No.7 bars in part (a) are in compression and theconcrete is lightweight. Also assume that the providedAs is 10% higher than the requiredAs.
