A 6.6 magnitude earthquake in xinjiang steel structures Chile seismic room let earthquake into floating clouds

A 6.6 magnitude earthquake in xinjiang steel structures Chile seismic room let earthquake into floating cloudsChina seismological bureau news says, xinjiang 6.6 magnitude earthquake has caused 34 people were injured, including one of them seriously. 217 national highway section XinYuanXian mountain collapses, about 120 people were stranded. The disaster area about 4735 houses damaged, which collapsed houses about 104 households, the dangerous house about and family. By 30 12, xinjiang region were recorded to aftershocks 189 times, of which 3.0-3.9 magnitude 9 times, 4.0-4.9 level 1, the biggest magnitude 4.2 aftershock.
According to the China earthquake networks determination, June 30 5, 7 points of yili kazak autonomous prefecture XinYuanXian Mongolian autonomous prefecture, the general HeJingXian border massive 6.6 magnitude earthquake.
China earthquake activity of high frequency, intensity, light source, widely distributed, is a serious earthquake country. Earthquake and other natural disasters constitute the seriousness of one of China's basic national conditions. And seismic room has also made some earthquake has become a floating clouds, protect the home at the same time, also protect this our security.
Earthquake resistant structure building and earthquake resistance steel structure seismic highest level
Features: steel structure is steel as the main structural material. Steel is characteristic of high strength, light weight, and at the same time as the steel material homogeneity and strong toughness, can have large deformation, can well under dynamic loading, has the very good aseismic capacity.
Application: but, due to the steel structure building cost is relatively high, the application is not very common.
General above 100 m tall building or span large buildings are normally used steel structure, shenyang is the typical steel structure building WuAi market for the second phase of shoes and hats market.
Shear wall structure seismic level take second place
Features: shear walls are made of reinforced concrete wall panel to undertake all kinds of load caused by the internal force, and can effectively control structure of the horizontal force, shear wall to inherit the vertical and horizontal force structure called the shear wall structure.
Application: in high-rise shear wall structure (height more than 24 meters buildings or ten layer, and the layer above the residential building) house is a large number of applying.
Frame structure seismic grade third
Characteristics: the reinforced concrete casting into bearing beam composition skeleton, reoccupy brick or prefabricated aerated concrete, ceramsite and light plate for individual partition assembly and into. The wall is mainly the containment and isolation effect, due to the wall not bearing, so can be made by all sorts of lightweight materials.
Frame structure, still have a kind of frame shear structure, also known as frame & ndash; Shear wall structure, it is frame structure and the shear wall structure with two system, drawing on their respective strengths, both for building layout provides greater use of space, but also has good resistance performance. The structure of the housing has good resistance to shock.
Application: frame structure in the modern architectural design are widely used, we can see most of the buildings is frame structure.
Brick and concrete structure seismic level generally
Characteristics: the who and brick and concrete structure, Brick and throughout , it is to point to a kind of uniform size of construction materials, including other size different clay brick, tile, etc. And who Mix and throughout It is to point to by steel, cement, sand, water preparation according to a certain proportion of reinforced concrete ingredients, including floor, lintel, stair, balcony. These parts and the main wall brick combination, so called brick and concrete structure. Brick and concrete structure housing general with multilayer (24 meters, residential 10 layer below) housing is given priority to, the seismic performance compared with the above three relatively weak some.
Application: brick and concrete structure, normally used in multilayer or span not big buildings, but as a result of brick and concrete structure building pattern rigid, metope can't change in recent years, and the frame structure and the shear wall structure application more and more common, in the urban construction has been rarely used brick and concrete structure, at present our country only a few of the buildings in the suburbs or brick and concrete structure.
Therefore, as a country, we earthquakes are common in casting self beauty home at the same time, but also more comprehensive factors to consider. The real life to make home care treasure
