【正文】 t least not as it is now present in people before such terror. Overseas Chinese Affairs department in Sichuan Province is located in the hardest hit of 69 overseas Heart School, the survey found. 41 damaged schools, including severely damaged 18 of 23 slightly damaged, none of the overseas Chinese schools collapsed heart. According to experts in emergency assessment of back stress, all brick structure for the casting slab and add columns and by formal design and the quality of the good did not collapse, much less steel frame structure and a. Seismic structure is the last line of defense, this view of the structure of choice for building seismic performance of unusual. 2. Earthquake with the choice of structure Earthquake collapsed houses, brick and concrete structure accounts for most of the first analysis of the masonry structure. Brickconcrete structure is a hybrid structure, with brick walls to load, due to the construction, low construction costs because, for decades has been the traditional form of Chinese civil, more suitable for deep bay into a small housing area is small, multi or lowrise buildings. Good pression performance is one big advantage, but also highlight its shortings: Since the major, low intensity, so that masonry structures subject to earthquake forces is relatively increased。Seismic zone to the framework of the civil from the brick necessary for the development trend 【 Abstract】 Earthquakes are inevitable natural disasters,but the choice of building structures which can effectively reduce the losses caused by the current seismic zone in construction, particularly in economically underdeveloped areas of the brick building structure, but its poor ability to contribute to the seismic earthquake39。 stoves, heavy, and basic use of artificial masonry, large amount of labor, inefficiency。s imagine, if they use a frame building in Wenchuan, designed by 7 degrees, such as to reach 9 degrees, has just reached the edge of destruction. If the actual quake was 10 degrees, although more than ultimate strength, but structural cracks, the stiffness decreases rapidly soften the structure, resonance no longer exists, the earthquake force is also smaller. And yield strength for steel, after more than there is ductility, although the broken concrete, the saying goes, a broken bone still attached tendon, the structure has not pletely collapsed, plus ring beam, structural support columns, damage extended, as long as not sleeping at night, there should be some room for shelter and leaving valuable escape time, then the earthquake in the number of our patriots will not go away. 【 Reference】 [1] Chen Cuirong.
