| Research Abstract |
In this study, related to evaluations of ocean environmental forces on huge marine structures, following topics have been investigated.
1,Abnormal environmental forces due to Tsunami and sea shock and dynamic responses of huge marine structures.
2,Numerical calculations on 1^<st> and 2^<nd> order hydrodynamic forces on multi-body floating system.
3,Hydroelastic behaviors of huge marine structures with column support.
4,Experimental technique of very small tank test for huge marine structures.
Related to design of ship and marine structures, following topics have been investigated.
1,Computer simulations on non-linear dynamic responses of multi-body floating systems in the seas.
2,Evaluations of relative wave heights and deck wetness of sea going ships.
3,Flare slamming of sea going ships.
4,Effects of column arrangement of huge marine structures on hydroelastic response in waves.
5,Human Impacts on Benthic Organism.
