We have discussed a relationship between damage ranks with different criteria for wooden buildings. First, criteria to judge damage ranks were reviewed using investigated materials of building damage from the 1891 Nobi earthquake to the 1995 Hyogo-Ken Nanbu earthquake. These criteria were classified into two types of the investigation by a police or an administrative office and the investigation by members having a profound knowledge on building damage. These criteria of the investigation by the police or the administrative office were almost same regardless of the generation in the material. Next, comparing vulnerability functions based on damage data of wooden buildings during the 1995 Hyogo-Ken Nanbu earthquake with those based on the damage data during the past earthquakes, these criteria didn't quite correspond in quantitative consideration. Finally, we have discussed the relationship based on building damage data of three investigations during the 1995 Hyogo-Ken Nanbu earthquake. These investigated organizations were Architectural Institute of Japan, Special Committee for Earthquake Reconstruction and City Planning, and Kobe city. Comparing damage data with vulnerability functions, we have pointed that the relationship were influenced by the purpose of investigations.
