1. Tsunami Effects On Coastal Structures

2.  Project description.  Work completed.  Results.  Work to be completed.  Summary.

3.  Impact of a wood log hitting a concrete column in: a- Longitudinal direction. b- Transverse direction.

4.  Design safer buildings, bridges, roads, etc.  Safe human lives.

5.  Wood log is 20 ft. in length and 0.8 ft. in diameter.  Concrete column is 12 ft. in length and 1 ft. in diameter.  The model contains 10000 nodes and 9500 elements.  The wood log is traveling at 2.68 mph or 3.931 ft./sec.  The distance between the wood log and the concrete column is < 1 foot apart.

8.  Wood log of the transverse impact needs: a- Addition of more solids elements. b- Modeled with the correct physical properties. c- The contact between the wood log and the concrete column must be face to face contact.

10.  During this summer I will be modeling a wood log hitting a concrete column.  I was able to obtain reasonable result for the longitudinal impact.  The same physical properties used to model the longitudinal impact will be used to model the transverse impact of a wood log hitting a flexible concrete column.
