What house is safer to live in when earthquakes strike? From wenchuan and yuko to the great earthquake in japan, to the recent frequency of earthquakes around the pacific. Housing resistance has become a hot topic and has attracted increasing attention, from building to buying houses. 512 days of disaster prevention and mitigation, the shanxi earthquake department teaches you how to live safe from earthquakes。
Pick a building and watch the earthquake
In advertising by provincial and city real estate developers, anti-earthquake houses have from time to time become the head of numerous commercial campaigns. What's the real earthquake room? The chief of the earthquake defense division of shanxi province stated that the houses that met the earthquake-proofing requirements had a bearing on their location, their geology and the houses themselves。
“there are now more developers to conduct earthquake-resistant tests before project design starts. In the past, some developers have been reluctant to spend money and have been less motivated to apply for earthquake-resistant reports, and society and the government have paid more attention after the wenchuan earthquake.” at the earthquake defense branch of the department of earthquakes, an anti-earthquake defence report was obtained from a jinyang street block to assess that the site met the 8-degree earthquake resistance requirements of the taiwon region and that the structure of the major earthquake would not collapse, but that measures would need to be taken to prevent the dehydration of sands following the earthquake。
At present, not all buildings are subject to earthquake-resistant reporting. In general, earthquake-resistant reports should be made on the formation of specially high layers or geological conditions, priority, lifeline engineering, and densely populated public places. The results of the anti-earthquake report, which assesses the location of their selection to allow the building to be built in a favourable manner, have to be replaced by a site or ground-based special treatment and re-construction. Earthquake-resistant and approved buildings are required, and seismic units provide seismic parameters for the location to enter the planning design and construction process。
Choice of housing
People want to buy a house that is earthquake-resistant, and developers want to choose an earthquake-resistant site that is less risky. In the case of the provincial city of taiwon, the city's buildings are protected against earthquakes of 8 degrees, and as long as the location and quality of the buildings are fully qualified, they should meet this requirement and accommodation is safe。
Sites that are not suitable for housing include activity faults and surroundings, water-saturated pine sands, soft mudslides, soft artificial coatings of soil, ancient waterways, old ponds, river beaches, steep slopes that are vulnerable to fragmentation and slides, thin pyres, hijabs or three surfaces facing water fields. Prudence is required to fill trenches or to build buildings on riverways。
People buy houses to find out whether the premises are secure, first, to see whether the formalities are complete and then to call the department responsible for earthquakes, construction, etc. The building's ability to withstand earthquakes is well known. In relative terms, low buildings are more resistant to earthquakes than high buildings, towers are more resistant to earthquakes and rafts are more resistant to earthquakes than strips and individual foundations。
Houses are now structured in a variety of ways, ranging from strong to weak earthquake resistance to steel structures, framework shear wall structures, frame structures, brick mixing and prefabricated structures. The magnitude 6 earthquake caused the collapse of a large number of prefabricated houses in local villages, which were less resistant to shocks. The new buildings in the city of taiwon are now based on concrete framework structures, and the design requires an 8-degree earthquake resistance, with the old buildings being reinforced or dismantled. Earthquake resistance levels vary across the province and construction requirements vary. For example, building a building at the same height, with a wall that is thicker than long cure in taihara, with different steel and cement requirements and higher costs, is the intuitive difference between earthquake resistance。
It's stronger than an earthquake
What building in the province has the highest level of earthquake resistance? High-level writing buildings or high-level residences, train stations or airports? None of these answers。
He said that in the aftermath of the wenchuan earthquake, we had imposed a level higher on schools and hospitals in public places. Similarly, the construction of a building and the construction of new schools, hospitals and steel skeletons are thicker and more intensive than the equivalent of general civilian buildings. Construction requirements vary from one industry to another, with special provisions. Schools and hospitals have higher earthquake-resistant requirements than other places。
The lower floors are more resistant to earthquakes than the higher floors, educational and medical facilities are more resistant to earthquakes than other public facilities of the same level, the new shanxi hospital is being built as a priority, the structure of the building is in the right place and the number of buildings is low. It is a major hospital building after the implementation of the new standards。
The new school building in taipa 62 was designed to increase the earthquake resistance of the school building through the introduction of thicker steel bars and reduced window space and pillar spacing. Steel structures have an advantage over concrete structures in terms of resilience and resilience, and are best resistant to shocks. The new tahara city museum, divided into five monolithic contours, is the most earthquake-resistant public space, both in size and structure; the multi-storey lobby of the hilton hotel has also been built with steel; and the hill medical college has expanded the waiting hall with high seismic capacity. In the almonds ridges, the owners, with their hands full, even flat repairs, use the entire steel structure, and the earthquakes are hard to shake. Large public goods buildings in the long wind business zone, with a large number of steel structures as the main subject, guarantee excellent seismic resistance。
The department of earthquakes and earthquakes, in the words of the chief of the seismic defense department, has introduced steel structures in the buildings and has significantly increased their resilience to earthquakes, albeit at a very high cost of inputs. In the course of the campus security project, the earthquake department found historical legacy, with schools built on faults in several schools in provincial cities and towns, which used relocations and concessions to avoid fault hazard. During the great earthquake in japan, solid buildings built on faults collapsed as a whole, while other buildings 100 metres away were safe, causing devastating damage to buildings on the ground.
