This is a special ad hoc seminar featuring two guest speakers. Both will be speaking in the same 50 minute period. This will be held in 1220B Kinsey Pavilion.

Seminar A: Large-Scale Shake-Table Test on Ten-Story Reinforced Concrete Building
Hitoshi Shiohara, Ph.D., FACI
Professor at the University of Tokyo, Japan

Abstract: A full-scale, ten-story, reinforced concrete building designed in accordance with the current Japanese seismic design code was tested under multi-directional shaking on the E-Defense shake table. Four three-bay moment frames are incorporated to resist to lateral load in longitudinal direction, while four shear walls resist to lateral load in transverse direction. When it subjected to JMA Kobe 100%  acceleration record, maximum story drift exceeded 3% and beam-column joint showed severely damaged while column, beams and shear wall remained with little damage. The behavior of beam-column joint and implication to current building codes are discussed.
Bio: Hitoshi Shiohara is a professor in the Department of Architectural Engineering of the University of Tokyo. He received his BS, MS and PhD from the University of Tokyo. His research interests include beam-column joints, precast concrete connections, and seismic design of reinforced concrete building structures.
Seminar B: Behavior of Retrofitted Buildings During the 2016 Kumamoto Earthquake
Koichi Kusunoki, Ph.D.
Associate Professor, Earthquake Research Institute, the University of Tokyo, Japan

Abstract: Japan has revised the Japanese building code several times. The revised code is not retroactively enforced on the existing buildings that were designed and constructed before the revision. In order to evaluate the seismic capacity of these older buildings, Japan has a seismic screening method, and has been conducting screening and strengthening/retrofitting since 1995 (Kobe Earthquake). In 2016, the Kumamoto Earthquake occurred at the Kyusyu Island, which is located far west of Tokyo. In this seminar, the outline of the evaluation procedures, a damage assessment overview for the Kumamoto Earthquake, and the behavior of retrofitted buildings will be presented.
Bio: Koicihi Kusunoki is an Associate Professor at the Earthquake Research Institute, the Univeristy of Tokyo. He has been serving as the Secretary General of International Association for Earthquake Engineering since 2014. Dr. Kusunoki received his BS, MS, and PhD degrees from The University of Tokyo, in 1992, 1994, and 1997 His research subjects are 1) Structural Behavior of Reinforced Concrete, 2) Structural Health Monitoring, 3) Seismic Design, and 4) Field investigation in earthquake affected area. Dr. Kusunoki received various awards for his work, including the “Excellence Award of Technical Design Competition of Architectural Institute of Japan” (Architectural Institute of Japan, AIJ), the “Encouraging Prize” (AIJ), and the “Encouraging Prize” (JCI).
