Abstract:: The building data of Hongta District of Yuxi City,Yunnan Province are collected by means of general survey and detailed survey.Then,on the basis of the data,the characteristics of the building structures and their seismic performance in Hongta District are summarized.And the evaluation formula of the buildings’ seismic capacity is established based on the seismic capacity index and the structural vulnerability matrix.The comprehensive seismic capacity values of the buildings in Hongta District are calculated on condition at that these buildings are hit by the earthquake intensity ranging from VI to Ⅹ degrees.The results show that the seismic capacity of the buildings is rated as “perfect”,“better” and “moderate” when the buildings are subjected to Intensity Ⅵ,Ⅶ and Ⅷ.When they are stricken by Intensity Ⅸ or Ⅹ,the seismic capacity of these buildings is rated as “poor”.
