NotesNumerical models were developed to run tests of tsunami impacts on bridge superstructures. The author also developed guidelines to estimate tsunami forces on bridge superstructures. The study focused on the Spencer Creek Bridge on the Oregon Coast, and three bridges on Siletz Bay, at Schooner Creek, Millport Slough and Drift Creek. β€œThe time-history of the numerical results show that, given identical tsunami conditions, box section bridges have to resist significantly larger forces (both horizontal and vertical forces) than the deck-girder section bridges. Therefore, it would be more appropriate to select deck-girder section bridges in the tsunami run-up zone instead of a box section. Furthermore, an effect of bridge rails to tsunami forces was examined in this research. The results showed that rigid rails on the superstructure could increase horizontal and vertical tsunami forces up to 20% and 15%, respectively.” (p.37) Includes drawings of the bridges studied.
