Welcome to the website of the Society for Earthquake and Civil Engineering Dynamics (SECED). SECED was founded in 1969 to promote the study and practice of earthquake engineering and structural dynamics, including blast, impact, and other vibration problems. SECED is also concerned with the study of societal and economic ramifications of major earthquakes.

This paper presents a brief overview of the current knowledge and research gaps in the evaluation of tsunami forces on coastal structures. It presents the need for a systematic analysis of the physics of tsunami flows in and around buildings and the forces and pressures they produce on structures as a function of time. The first steps towards such a study are presented. Through a combination of large-scale physical experiments reproducing the forces generated by extremely long, tsunami-like, waves on instrumented building models, and small-scale tests of steady flows around rectangular cylinders, it is shown that steady-state approximations of drag force can potentially represent the unsteady case of tsunami flows around buildings. Significant limitations surround this observation and hence, plans to continue the study are presented.
