Erratum for “Energy-Based Liquefaction Triggering Model”

The following correction should be made to “Energy-Based Liquefaction Triggering Model” by K. J. Ulmer, R. A. Green, A. Rodriguez-Marek, and J. K. Mitchell, https://doi.org/10.1061/JGGEFK.GTENG-11402:

Eq. (21) for the factor of safety against liquefaction triggering ($F{S}_L$) is incorrect and should be replaced by the following equation:where ${(\mathrm{\Delta }W/{\sigma }_{vo}^{\prime })}_{\mathrm{liq}}$ is estimated using Eq. (20). For cases where $q_{c1Ncs}>180$, $q_{c1Ncs}=180$ is used in conjunction with Eq. (20) to estimate ${(\mathrm{\Delta }W/{\sigma }_{vo}^{\prime })}_{\mathrm{liq}}$.

Alternatively, $F{S}_L$ can be estimated from the probability of liquefaction triggering ($P_L$) using the following equations:where $a=0.821$; $b=3.15$; and $P_L$ is estimated using Eq. (19).

Eqs. (21a) and (21b) result in approximately the same values of $F{S}_L$, with Eq. (21b) tending to yield slightly larger values of $F{S}_L$ than Eq. (21a) for $F{S}_L>2$.

The authors apologize for the oversight of not correcting Eq. (21) before publication and assure readers that no other part of the paper’s content or conclusions is affected by this.

To preserve the published version of record, these details have been corrected only in this erratum.
