Profile Hidehiko Sekiya is an associate professor in the department of Urban and Civil Engineering & Advanced Retrofit Technology International Center at Tokyo City University in Tokyo. He obtained his BEng and MEng from Tokyo Institute of Technology in Tokyo and Dr. Eng. from Tokyo City University. He started his research work in Tokyo Institute of Technology where he investigated the bending performance of HYBRID steel girder. After he obtained Master degree, he have been working in design department of the liquified natural gas for 2 years. His current research activities include structural health monitoring using variou lates sensing technology.
Research Field(Keyword & Summary)
  1. Structural Health Monitoring, Maintenance, Sensing, Steel Structures

    He is studying structural health monitoring using variou lates sensing technology. For example, in the maintenance of steel bridges, it is important to know the magnitude and the number of live loads. Therefore, he is studying Bridge Weigh-In-Motion using MEMS accelerometers. Furthermore, he is trying to identify the deformation of steel bridges using sensing technology. The identified deformation is useful for the maintenace of fatigue damage.
