T2R2 open-access full-text files surpass 2,500 mark!


January 28, 2015

The Tokyo Tech Research Repository, or T2R2 is a unified system for the registration, storage, management and dissemination of papers, articles, books and other academic work published by researchers at Tokyo Tech, and the metadata (bibliographic information) for work published by individuals affiliated with the Institute. All materials in the system can be searched and read by users both on and off campus.

The number of T2R2 full-text files accessible to the public exceeded 2,500 on October 18, 2014, and we would like to express our sincere gratitude to all the researchers whose contributions helped Tokyo Tech to achieve this milestone. The T2R2 system will continue facilitating the dissemination of research being carried out at Tokyo Tech. We appreciate your continuing use of the T2R2 system and your cooperation in data input and file registration.

The 2,500th paper registered in the T2R2 was published by Associate Professor Daiki Sato of the Materials and Structures Laboratory.

Please give a summary of your paper.

It is possible that high-rise buildings constructed before the 1980s may suffer significant damage in long-period ground motion. This paper describes testing conducted with E-Defense, the world's largest shake table, to verify the actual damage that can result to such structures during significant earthquake. E-Defense is capable of shaking (via long-period ground motion) a full-sized model of the lower portion of a high-rise building constructed in the 1980s. This paper also describes the effect of reinforcement using a vibration control device (damper).

Who are the readers being targeted by this publication?

In addition to researchers in structural engineering and earthquake engineering, this study may be of interest to researchers and students in other fields.

What research are you planning in the future?

There is concern that a massive earthquake emanating from the Nankai Trough may strike in the foreseeable future or that such a large quake may even hit the Tokyo metropolitan area directly. This prompted my interest in research on vibration control structures and base-isolated buildings that can be used immediately following an earthquake to protect human lives and building functions.
