The earthquake damage to the buildings and structures in the Yao’an, Dayao, Nanhua and Mouding counties was systematically investigated in the extremely seismic zone (Ⅷ degree) of the Yao’an M6 5 earthquake and the earthquake damage. As one of the systematic researches, the seismic destruction phenomenon of multi-story reinforced concrete frame, multi-story masonry, bottom frame, brick and wood structure, civil and housing structures, single-story workshop and brick tower is described. The characteristics of earthquake damage and the main impact on the earthquake damage to the building. The problems, experiences and lessons that should be paid attention to in earthquake prevention and reduction in the urban construction of the earthquake area are discussed.
