2、 103.48°) occurred in 8.0- level large earthquake focal depth of 15km, the epicenter degree of intensity up to 1l. The earthquake caused surface rupture zone length of more than 200km, th

3、e mountains and rivers were also improved, roads, bridges, buildings and other facilities for various types of projects were listed out in full damage. At the same time, due to Wenchuan disas

4、ter areas with natural geographical conditions of geological structure is very complex, a major earthquake caused a large number of landslides, collapses and other geological disasters. The devas

5、tating earthquake were strong, spread widely, leaving a total of Si Chuan, GanSu, ShanXi, ChongQing and other 10 provinces (municipalities), more than 400 counties (cities, districts) affected to

6、 varying degrees, in particular the widespread destruction of buildings, according to Statistics alone there are more than 1,400 houses collapsed 10000, resulting in huge losses. An County in Si

7、Chuan Province was hitted heavily by the earthquake, Buildings had been designed in accordance with the “Seismic Design of Buildings“ of different time. Some buildings of the earthquake intensit

8、y is 6 degree, a small number of seismic fortification intensity of 7 degree. As the County ground motion intensity, building damage is very serious. Earthquake damage is very typical for eart

9、hquake engineering, which provides valuable material for study of earthquake damage to the engineering theory and engineering practice. In this thesis, the works collected in the County to condu

10、ct an overview of earthquake damage, discussion of different forms of destruction of the structure and characteristics of the phenomenon, and gives in- depth analysis. After the earthquake, I res

11、ponded to the CYL Central Committee and other relevant departments's call, went to An County in SiChuan Province to participate in earthquake relief volunteer service, duration up to 1 year

12、. I studied in the earthquake disaster affected areas to carry out seismic surveys, housing security cointingency assessments, special housing structure, technical appraisal and technical personnel

13、 training, etc., to master a wealth of housing first- hand information on earthquake damage assessment survey. This thesis is based on seismic design theory and knowledge , engineering practice,

14、 based on on- site inspection, with emphasis on the County District masonry structure houses, frame houses to be describing the phenomenon of earthquake damage, earthquake damage to its overall

15、summarized, and damage to housing cause analysis, obtained seismic measures to improve housing and appropriate measure. The main contents of this thesis include: “5.12“ Wenchuan earthquake in a
