Abstract:

The load effects on a coastal bridge due to the impact of a tsunami wave were developed. Three Cascadia Fault

rupture scenarios were considered using the Cornell model and the FVWAVE model to generate the waves for

each scenario. The FVWAVE model for the worst case rupture scenario was used to develop the load effects.

Fluid-structure interaction analysis was conducted with the computational mechanics software LS-DYNA to

create a time-history of the lateral and uplift pressures on the bridge deck. From the pressure data, a time-history

of the lateral and vertical reaction forces on the columns was plotted. The computations were conducted in two

dimensions, but work will continue for three dimensional modeling that will incorporate the applied pressures on

the columns.
