An error was introduced into Eq. (2) during typesetting of this paper. The operator in the second line of the set should be , as follows:
χi(y)={1ifyAi0ifyAiwithi=s,c
(2)
An error was introduced into Eq. (6), whereby the minus sign was not included within the horizontal brace for Mc(x). The equation should have read
M(x)=Esbt36ϕs(x)Esbt22[cϕc(x)+tϕs(x)]Ms(x)Esbtc2[cϕc(x)+tϕs(x)]Ecbc312ϕc(x)Mc(x)
(6)
Two errors were also introduced into Eq. (18), with one of the subscript terms and one exponent in a denominator being typeset online. The corrected equation is
f(ξ)=24C0k4[ek11e2kek(ξ1)12(cothkcschk+1)ekξ]+C0ξ42C0ξ3+12C0k2ξ2+C0(112k2)ξ+24C0k4
(18)
ASCE regrets these errors.
Additionally, the right-hand sides of Eqs. (19), (20), and (23b) should be of opposite sign, as follows:
ϕ(ξ)=β1α2β2α1L3d3f(ξ)dξ3+β1β3β22α1β2Ldf(ξ)dξ,ψ(ξ)=1L3d3f(ξ)dξ3υ(ξ)=α2β2L4d4f(ξ)dξ4(β3+β1α2α1)1β2L2d2f(ξ)dξ2+β1β3β22α1β2f(ξ)β2=AG(y)dw(y)dydA
In the unnumbered display equation following Eq. (29) on p. 505, the denominator of the first fraction should be multiplied by k, as follows:
A2stakA3=3L4c1+4ε+4ε21+6ε+12ε2+8ε3=3L4c11+2ε=3L4h
Finally, in the Krajcinovic (1971) reference, the publication year should have read 1972. Citations to this reference appear on pp. 502, 503, 504, 505, and 507 of the published article. The corrected reference appears in this erratum.
