Abstract
To reduce the damage of structures caused by tsunamis, it is essential to know the characteristics of tsunami load. In the present study, a three dimensional hydraulic experiment was performed to investigate the spatio-temporal variation of the tsunami wave pressure acting on a land structure. The followings were found out.
(1) Wave pressure can be regarded as the sum of the average component and the random component of pressure.
(2) The spatial distribution of wave pressure for 3-D experiment case is similar to that of 2D case.
(3) Wave pressure distribution depends on not only run-up depth but also water surface steepness.
(4) Random component of tsunami wave pressure is impulsive.
