The Application of Fuzzy Mathematic in Earthquake Damage about Ancient Buildings

Ancient buildings have poor anti-seismic ability due to the long age of construction and lack of data materials. This paper seeks a scientific and quantitative evaluation method and predicts the earthquake damage of an ancient building by using fuzzy analogy approach. The example shows that this evaluation method has great meaningful of the existing ancient buildings under the earthquake intensity which likely to be encountered with the design life expectancy and provides a certain scientific basis of seismic estimation in ancient buildings.
