In this research, first of all, we clarified the tendency of the structural characteristics (i.e. building scale and weight, dimension of columns, dimension of walls) of the existing historic buildings in Tochigi City, based on actual survey data of the past. And the vibration characteristics of historic buildings in the northern Kanto region were evaluated by the vibration measurements. Then we evaluated the maximum horizontal proof strength and this base shear coefficient of the warehouse structures. Finally, we proposed the method for estimation of the maximum base shear coefficient from the natural period.
