EXPERIMENTAL AND NUMERICAL SIMULATION OF TSUNAMI BORE IMPACT ON A BUILDING

Buildings must have well design against tsunami impact to mitigate the damages. This study presents the numerical simulations of tsunami impact on a building model structure. Series of experiment were carried out in the laboratory for a simple building model structure for different initial tsunami bore heights. Numerical simulation with the newly improved three-dimensional moving particle semi-implicit (3D-MPS) method performs here to validate with the physical experimental results and also comparing with the original MPS method. The newly improved 3D-MPS method shows good qualitative and quantitative agreement with the experimentally recorded pressure and height. Consequently, tsunami bore impact on the building model structure was investigated by the numerical simulation. The changes of the tsunami bore height and velocity around the building model structure has been found which can lead to varied tsunami bore impact. This study can help in understanding the mitigation against the tsunami bore impact around the coastal houses and infrastructures.
