| Summary: | Tsunami surges create catastrophic damages to buildings in considerably large coastal areas. Tsunami that surges inland eventually hit buildings with high impact and drags force that normally beyond the design capacity of the structures. Many researchers have conducted experiments regarding the interaction between tsunami surge and structure using physical modeling in laboratory and numerical simulations.
Smoothed Particles Hydrodynamics (SPH) is a numerical method in two and three dimensions of fluid dynamics equations by replacing the fluid with particles. This numerical method is a powerful tool to obtain much detail quantities such as pressures, velocities and free surface elevations around the structures during the event of tsunami attack.
This research is a part of the initial study of the first author’s PhD thesis. The research investigates the performance of three dimensional numerical simulation model using SPH to estimate hydrodynamic quantities around a structure. The results show the agreement between the numerical solution and the physical model results in term of surge speed, and tsunami surge force.
