Description

It is necessary to take account of transitional fluid force when tsunami collides against a pipe installed ashore. In this study, experiments by dam-break method were carried out to grasp characteristics of fluid force by tsunami acting on a horizontal pipe. The measurement results were compared with the results of CFD analysis, revised equation adding impulse force and fluctuating fluid force to Morison equation, and drag force equation shown in the guideline of Federal Emergency Management Agency (FEMA) to build a reasonable evaluation methodology of wave force by tsunami acting on a pipe, and to evaluate margins by each method. Consequently, evaluated maximum values of wave force to experimental results were 0.8 to 1.8 times in CFD analysis, 1.4 to 2.1 times in revised Morison equation, and 2.1 to 6.1 times in FEMA's guideline.
