Abstract: In response to the catastrophic effects of recent tsunamis on coastal bridges, this study presents a smart experimental setup that enabled the hydraulic testing of the largest skewed superstructure to date. The data demonstrate the importance of the three-dimensional effects and resultant yaw and roll moments, which overload the individual abutments. This in turn suggests the need for a paradigm shift in the assessment of tsunami risk to coastal bridges to include not just the estimation of maximum total forces but also the consideration of multiple load cases with appropriate combination of forces and moments that will represent the most critical instants of the complex 3D tsunami-bridge interaction of skewed superstructures. 1.
