Notes

See FEMA (2010), Table 8.9 (page 8-16). It is also used for tanks in refineries (Table C.8.2, page 8-99).
Eidinger et al. (2001) indicates that the curves are applicable only for (water) tanks that are at least 80% full at the time of the earthquake (Part 2, page 78).
See Di Carluccio et al. (2006) Table 2 (page 219) for probit constants, which supercedes Salzano et al. (2003) Table 5 (page 408).
In Salzano et al. (2003), curve parameters for ≥DS4 are wrongly indicated as 1.06 and 0.8.
