Abstract:On the basis of the field investigation of 355 points in the earthquake-stricken area of the Jinghe MS6.6 earthquake on August 9, 2017, we determined the intensity distribution of the earthquake. The highest intensity of earthquake-stricken area is Ⅷ degree(8 degree). The area is 15, 623 square kilometers, and the total population of the disaster area is 487, 696, among which 133, 695 people were affected by the disaster, and 36 people were injured in the earthquake. We sorted out the earthquake damage of different structure types of houses in different intensity areas, and analyzed the seismic capacity and cause of damage of different structure types of houses. The results show that the collapse of civil structure housing and eaves collapse is the main cause of personal injury. Brick-wood houses lack seismic equipment and have diversified forms of destruction. Brick-concrete houses are seriously damaged in high intensity areas. The main body of the frame structure is intact but the filling wall is generally damaged. Buildings constructed under "Urban and Rural Anti-earthquake Project" has good seismic performance.
