| Research Abstract |
Dynamic loading test is useful for the advancement of earthquake engineering. Due to high cost among others, dynamic loading systems are commonly limited in size. Needs for dynamic loading test, however, increases in conjunction with the development of various damping devices used for mitigation of earthquake disasters. This study develops methods that increase the power, i.e., the displacement, velocity, and frequency capacities, of shaking tables, by the addition of extra segments that are connected to the shaking table. A displacement enhancing segment is developed by a combination of linear roller sliders and ballast, while a frequency enhancing segment is developed by the production of continuous collision between two spring-mass systems. To ensure accurate response on the segment, various control algorithms are developed. Effectiveness of the proposed system is examined for the behavior of medical appliances installed in a base-isolated medical facility.
