The Hanshin-Awaji Earthquake (January 17, 1995) clearly demonstrated that the occurrence of very strong ground motion in the area near to the seismic fault is capable of causing severe structural damage beyond general estimation. It has emphasized the importance of earthquake engineering research into why and how structures collapse in real earthquake conditions. Considering the lessons learnt from recent earthquake disasters, National Research Institute for Earth Science and Disaster Prevention (NIED) plan to construct the 3-D Full-Scale Earthquake Testing Facility (E-Defense id\s the nickname of this facility), which will be able to simulate the process of destruction of structures under the condition of real strong earthquake motions. The basic performances of E-Defense are maximum lording capacity 1,200 tons, maximum velocity 200 cm/s and maximum displacement 2 m p-p for two horizontal excitations and maximum velocity 70 cm/s, maximum displacement 1 m p-p for vertical excitation to realize destructive ground motion. The construction work of E-Defense has begun at early 2000, five years after the Hanshin-Awaji Earthquake and will be completed at the beginning of 2005, ten years after that Earthquake. Now, we are conducting the construction works of the facility at the Miki-city, near Kobecity, and the manufacturing and installing of actuators, oil-pressure supply system and other parts of shaking table by the Mitsubishi Heavy Industry Co. E-Defense is the very large scale and high performance testing facility in the world. Therefore, many researchers, which are belonging not only Japanese but also worldwide organizations, can use this facility for their researches. E-Defense should be operated the international common use. For the international research collaboration and the dissemination of research results (including test data), E-Defense Network (ED-Net) will also construct until the completion of E-Defense. ED-Net will connect, through a high performance Internet, distributed major earthquake engineering research organization. We consider that the researchers together from worldwide and research projects will determine and evaluate by the Committee. We hope that E-Defense and EDNet will be situated to one of the cooperative research organization for the earthquake disaster mitigation in the world.
