ZHANG Xiaokui;Beijing Tsinghua Tongheng Urban Planning & Design Institute;  
Taking the city center of Tangshan city as an example,based on the analysis of the seismic capacity of urban buildings under the earthquake intensity,the reconstruction of the Tangshan earthquake in 1976 was carried out. The present situation of Tangshan city center was analyzed. Earthquake resistance under earthquake. The results show that the general situation of the central city of Tangshan city,the overall construction of the basic to meet the requirements of seismic fortification. When the terrible earthquake,the proportion of buildings that were destroyed was 33. 84%. The results of the analysis of the earthquake in the tunnel are better reflected in the situation of the central city of Tangshan city to meet the national requirements of seismic fortification capacity,and extremely rare earthquake analysis results reflect the Tangshan city center city is facing the risk of exceeding the fortification earthquake intensity. They complement each other,a comprehensive understanding of the central city of Tangshan city,the general building seismic capacity has a certain practical significance.
