Abstract
  • Impact by an idealized shipping container on a column were observed for tsunami flow in a large-scale wave flume modeled at the O.H. Hinsdale Wave Research Laboratory at Oregon State University. Two specimen types, aluminum and acrylic, were tested; and each specimen was tested in two orientations, longitudinal and transverse. The debris specimens were constructed to be 1:5 scaled versions of standard shipping containers with container capacities of one twenty-foot equivalent unit (TEU). Hydraulic experiments were compared with corresponding in-air impact experiments using the same experimental configuration to assess the hydrodynamic effects in increasing the impact force. Experiments were conducted by varying flow conditions, velocity, nonstructural mass, impact angle, and debris specimen material. Hydraulic Longitudinal Aluminum Test results showed a 10% increase in measured impact force when compared to the corresponding In-Air Test. Transverse Aluminum and Longitudinal Acrylic Tests showed upwards of a 40% increase in measured impact force when compared to their corresponding In-Air Tests. The impact durations measured from the in-air test provided a lower bound for the impact duration measured for the in water tests. Hydraulic effects were shown to increase the impact duration by an average of 20%. Nonstructural mass was shown to have no significant impact on the measured peak impact force, however an increase of non-structural mass appeared to increase the measured impulse as expected.
