State of the Art of Shaking Table Tests of Wood Buildings in Japan


In the last decade, many shaking table tests of wood buildings including collapse tests have been conducted in Japan. The purposes, results, conclusions and video clips of these full-scale tests are presented in this seminar. The various test structures included:

  1. New houses with/without non-structural elements designed according with minimum seismic provisions of the current Japan building standard law.
  2. New houses including American style light-frame (2x4) construction designed by one of the biggest home builders in Japan.
  3. Existing houses removed from their locations and re-constructed in the laboratory.
  4. Simple models using viscous dampers and elasto-plastic rubber-based joint dampers.
  5. 2-story and scaled 5-story hybrid structures consisting of reinforced concrete and wood structure. Besides the shaking table tests, analytical studies to predict the behavior of the test specimens will be presented.

Short Biography

Dr. Hiroshi Isoda received his Ph.D in Faculty of Engineering from the University of Tokyo in 1995. From 1990 to 1995, he was a Faculty and an Assistant Professor in Architecture and Civil Engineering at Shinshu University where he taught in the area of Structural Engineering. He moved to the Building Research Institute (BRI), National Institute of Japan, as a Senior Researcher in 1995. In 2000-2001, he was also Visiting Researcher in the Department of Structural Engineering at the University of California in San Diego, where he analyzed the seismic response of four index wood buildings within the FEMA-funded CUREE-Caltech Woodframe Project. He is now Associate Professor in Architecture and Civil Engineering at Shinshu University and also Visiting Researcher in BRI.
