海洋構造物試験用2方向振動試験機に関する研究

抄録

As the ocean development has progressed, the studies for ocean structures have increased. With the process of those studies, it is necessary to develop the various testing machines for ocean structures. Especially, in the areas where the earthquake often occurs like Japan and West Coast region of the United States of America, we must naturally design a ocean structure considering the earthquakes. Therefore experiments with shaking a underwater model has become important. We have studies to make a new underwater biaxial shaking machine for ocean structures. It is used for measurement of added mass, resonance characteristics and dynamic pressure acting on a structure. This article tells about the designs of new type biaxial shaker.
