| Outline of Final Research Achievements |
The hydraulic test and the static loading test is carried out on the 1/20 scaled reinforced concrete standing wall specimens in order to evaluate the nonlinear response of the structure under the wave load. The different overturning moment strength is given by the position of the tensile rebar, while the specimen has identical shape. The strong specimen shows elastic response, and the weak specimen overturned by the identical tsunami wave load. The standard specimen deformed, but restore its original position after the yielding of the tensile rebar. The impulsive load was observed at the tip of the wave, and it was not effective to the strain of the tensile steel rebar. The overturning moment is consistent with the moment calculated with the hydrostatic wave pressure of water height in front of the specimen at lower water level, but it saturates the constant value when the water height shows three times higher than the inundation depth of wave without the object.
