碩士 / 國立成功大學 / 土木工程學系碩博士班 / 101 / The great earthquake of M_w=9.0 occurred on 11 March 2011, and subsequently caused the Tohoku-oki tsunami which caused devastating disaster in northeastern Japan and coastal towns. As the damaged nature disasters caused heavy casualties and economic losses, recently people have gradually paid their attention to tsunami issue.
As the laboratory subject to restrictions on the spatial scale, this study through CFD (Computational Fluid Dynamics Computational Fluid Dynamics) numerical simulations analyze the impact of water force on a residential building which are located on mildly sloping beaches.
In order to verify the feasibility of the CFD numerical methods, the velocity and wave height of the numerical simulations results were comparison with the measurement results.
And then, this study presents the numerical simulations investigation into the impact of tsunami during the run-up process on a beachfront residential building. The results shown that the highest wave height is 20.93m when tsunami reached ashore. Later, tsunami impact to the building. The pressure of tsunami on the bottom layer is up to 293063 Pa and at this time the maximum wave pressure is 414150Pa at about 4 meters height of the building.
