In this research, new seismic diagnosis method on microtremor observation in addition to seismic diagnosis is proposed. Microtremor observation, man-powered vibration test, motion exciter test (collectively called small-deformation test, or SDT) and shaking table test are examined at three wooden houses over several stages. The appropriateness for the usage of SDT as barometer of stiffness is evaluated from tests on specimen before and after suffering change of situation, for example, weight, aging degradation, shaking, seismic reinforcement. Magnitude correlation among secant stiffness of real-load-deformation relationship, stiffness on seismic diagnosis, skeleton curve of analysis model and stiffness on SDT is determined. It would provide help us establish seismic diagnosis method well reflecting actual condition of building.
