The beam centrifuge makes it possible to achieve the same stress condition of actual structures can be applied in a prototype by applying a centrifugal acceleration of N times of earth gravity (1 G), to a 1/N scaled model of the ground. Introduction of the beam centrifuge at the Naruo Research Center in 1984 was a world’s first by a private-sector company. Since that time, centrifugal model tests have been carried out to study a wide variety of technical issues required in the construction of civil structures such as large-scale marine reclamation, shield tunnels, and the development of aseismic construction methods, etc. Thanks to the accumulation of research on processes that are necessary for cutting-edge experiments, namely, advanced development and design of model ground preparation and loading devices, Toyo can respond flexibly to diverse needs.
- Possible to reproduce the same stress and strain as in an actual structures in small-scale tests.
- Use of small-scale models reduces the time and cost of tests.
- Equipped with a shaking table that supports tests under all types of earthquake motion, including Level 2, long period, and long time motion.
- Possible to grasp changes in the total system by image analysis with a high speed camera.
