Published Papers

Masayuki Kohiyama, Masashi Omura, Masaki Takahashi, Osamu Yoshida, and Koichi Nakatsuka
Japan Architectural Review   2(3) 226-237   Jul 2019   [Refereed]
The Sosokan building of Keio University located in Yokohama, Japan, is a base‐isolated building with a semi‐active control system. The semi‐active dampers’ damping coefficient is changed to best reproduce the optimal control force in linear‐quadra...
Design Method of Inter-Story Tuned Mass Damper to Reduce Story Deformation and Its Verification Tests
Masayuki KOHIYAMA and Masashi OMURA
Journal of Structural Engineering   65B 77-84   Mar 2019   [Refereed]
An inter-story tuned mass damper (ISTMD) is a variant form of a tuned mass damper, which is placed between consecutive floors to suppress the resonant response of a structure. We derived design parameters of an ISTMD under ground excitation that m...
Masayuki Kohiyama and Hiroki Yokoyama
Frontier in Built Environment   4(38) 1-12   Jul 2018   [Refereed][Invited]
Eccentric distribution of stiffness, damping, and mass of a structure, and spatially non-uniform ground motion input to a long or large base mat of a structure are well-known causes of torsional response. We have discovered that the torque generat...
Update of Control Parameters of Semi-Actively Controlled Base-Isolated Building
Kohiyama, M., Omura, M., Takahashi, M., Yoshida, O., and Nakatsuka, K.
Proc. 7th World Conference on Structural Control and Monitoring   351-359   Jul 2018   [Refereed][Invited]
The Sosokan university building has base isolation and a semi-active control system. The semi-active dampers’ damping coefficient is changed so as to best reproduce the optimal control force in linear-quadratic-Gaussian control. However, the imple...

Journal of Sound and Vibration   424 302-317   Jun 2018   [Refereed]
Many buildings in Japan currently have a base-isolation system with a low stiffness that is designed to shift the natural frequency of the building below the frequencies of the ground motion due to earthquakes. However, the ground motion observed ...
