The 2019 Full-Scale Shake Table Test Program of Wood Dwellings (original) (raw)

The 2019 full-scale shake table test program of wood dwellings is addressed in this paper. The current Japanese seismic design guidelines were applied and two Grade-3 index buildings were prepared. One adopted the Post-and-Beam Structure (A-building), and the other the Shear-Wall structure (B-building). A series of tests planned very different physical boundary conditions surrounding their reinforced concrete foundations. In the first Phase 1, A-building was equipped with a base-isolation system, while B-building represented a generic foundation constructed on real soil by preparing a rigid soil box. In the second Phase 2, the foundation of A-building was firmly fixed, while cast-iron plates were installed beneath the foundation of B-building to control the friction resistance of the foundation. In the third Phase 3, the damaged first-story of A-building was retrofitted, and the foundation of B-building was firmly fixed. The two test buildings were densely instrumented with both con...
