Are self-built houses in rural areas earthquake-proof? Is it safe? -wellcamp light steel villa manufacturers
New rural self-built houses, at this stage, many friends are concerned about whether the appearance of the house is beautiful, and the interior layout is comfortable or not, but the safety of the type of house structure is generally ignored. Many friends build houses by simply looking for a set of blueprints that look good on the Internet and building them according to them, or they will directly hand them over to the foreman in the village to make them look good. Compared with renderings and floor plans, as long as they are suitable, they can be used all over the country, but compared with structural drawings, they are not. This is because the fortification intensity and geological conditions of different regions are different. For example, the set of drawings you saw on the Internet was designed according to the fortification of 8 degrees, but in fact the fortification intensity of your building area is only 6 degrees. So if you use this set of drawings to build a house, it will increase the amount of decorative building materials, and thus increase the cost of building the house. On the other hand, if the fortification intensity of the area where you are building a house is 8 degrees, but the drawings are designed according to 6 degrees, then the house will have hidden dangers when it is built. The painful lessons of the Wenchuan Earthquake, I believe no one has ever forgotten. Seeing this, it is very likely that some friends will have questions, what is this fortification intensity? ? Does it mean the same as the seismic rating? What does it have to do with our building? Today, the new house is here to explain this kind of knowledge to you! What is the magnitude of the earthquake? First of all, let's talk about the magnitude of the earthquake. For example, we saw on the Internet that the Tangshan earthquake on July 28, 1976 had a moment magnitude of 7.5, and the Wenchuan earthquake on May 12, 2008 had a moment magnitude of 7.9. Therefore, the magnitude of this earthquake refers to is a property of an earthquake. If the same earthquake has different magnitudes reported on the Internet, it is due to the selection of different magnitude standards. China divides earthquakes into six magnitudes: small earthquakes of magnitude 3, felt earthquakes of magnitude 3 to 4.5, moderately strong earthquakes of magnitude 4.5 to 6, strong earthquakes of magnitude 6 to 7, large earthquakes of magnitude 7 to 8, and large earthquakes of magnitude greater than 8 are huge earthquake. What is the earthquake intensity? Take the Wenchuan earthquake as an example. The earthquake intensity in Wenchuan, the epicenter, was 11 degrees, 7 degrees in Chengdu, and 5 degrees in Chongqing. We can see that the earthquake intensity at the epicenter is higher, and the further it goes out, the lower it is. Does the seismic rating refer to the property of the area? When friends come to customize design drawings, they often say that our seismic grade is X. In fact, the seismic grade is not an attribute of the region, but an attribute of the building structure. The earthquake resistance level is divided into one to four levels, and the more important the building needs to be protected, the higher the earthquake resistance level. In other words, housing buildings of the same area, the same structure type, and similar heights, primary and secondary schools, hospitals, etc. are generally a higher earthquake resistance level than vegetable markets, ordinary office buildings, and residential buildings. What is the relationship between seismic fortification intensity and self-built houses? Later, let’s talk about issues related to our self-built houses——Seismic fortification intensity. Seismic fortification intensity refers to the seismic intensity that is permitted as a basis for seismic fortification in a region according to the authority stipulated by the state. In our country, the seismic design code at the current stage is fortification based on the intensity. Different regions have different regional planning, such as It is said that Beijing is fortified at 8 degrees, Nanjing, Jiangsu is 7 degrees, and Shaoguan, Guangdong is 6 degrees. The seismic fortification intensity is 6 degrees as a critical point. If the seismic fortification intensity of the area is 6 degrees and above, then seismic design needs to be done, and it is not required below 6 degrees. If you are interested in the seismic fortification intensity of your own area, you can search for the 'China Earthquake Parameter Zoning Map'. Building a house by yourself often takes most of a family’s life savings. We should invest our limited funds in the safety of the house, especially in areas with high seismic fortification intensity. Before building a house, try to find a professional design for simple life. The designer designs the drawings, and after the drawings are designed, the construction is strictly in accordance with the drawings. Safety issues, don't be sloppy! what do you say?
