- Abstract:
- The distribution of the seismic intensity of the Mojiang MS5.9 earthquake occurred on Sep.8,2018 in Yunnan Province is introduced,and the damage characteristics of buildings,the damage ratio and seismic damage index of various structure building in each intensity area are compared with those of the Chinese Seismic Intensity Scale. Then the main basis and method of seismic intensity assessment are discussed. It is concluded that the aseismic performance of all kinds of buildings in Mojiang earthquake disaster area is as follow: The frame structure is the best, brick-concrete structure is the second, traditional brick and civil structure is poor, and the hollow brick wall is the worst. The seismic damage indexes of each intensity area and investigation point correspond well with the intensity. The intensity distribution of the Yunnan Mojiang MS5.9 earthquake meets the national standard and the distribution law of seismic intensity in Yunnan. We suggest that the seismic intensity by field investigation should be based on the earthquake damage of the housing structure, which takes up a high ratio in the seismic intensity assessment. The earthquake intensity should be quantitatively evaluated by calculating the average seismic damage index of buildings.
