Shockproof construction will become the development trend of the Japan earthquake 2013-02-03 13:51:43 | Category: Default Category | Tags: | font size medium and small subscription.
Building materials businesses to benefit from Japan's post-disaster reconstruction, only short-term gains, but another, more thought-provoking earthquake awareness of our architecture is able to strengthen. The study of earthquake-resistant construction and shock-resistant material are enterprises or small industry alone for there is no authority for specialized research. China's building standards, not even related requirements.
In sharp contrast with Japan's earthquake, Yunnan Dehong Prefecture the Yingjiang recently occurred 5.8 earthquake, the county supermarket, hotel and many houses collapsed, most of the walls of the city collapsed. After the earthquake, many buildings, Yingjiang along cracks in the wall, the earthquake resulted in Yingjiang city most of the old houses collapsed. Many homes had the lowest level of direct collapse, the first floor of a three-story supermarket collapsed completely, the original second floor into the first floor.
Industry experts said that, look at the damage to infrastructure projects and buildings from a major earthquake, earthquake-prone, or to make China more thinking about building a solid and secure. From the steel building, the future of integrated housing will become increasingly favored by more domestic construction.
Frequent earthquakes will make the world more and more attention to the shock level of the building to become the focus of the industry in China has not been widely steel building can usher in the explosive growth. The data show that the 1985 Mexico earthquake and the 1995 Kobe earthquake in Japan, steel structures housing destruction rate and extent of the damage is far lower than the reinforced concrete structure housing. Because of the many advantages of the steel building, the developed countries, the proportion of annual steel steel has reached more than 30%, especially Japan, the proportion has reached 50%, while the proportion of China's steel structure housing in all residential buildings less than 1%.
Superior earthquake performance of steel building, especially residential steel structure, there are other features, which makes the industry is expected to receive state support. China's steel overcapacity forced to reduce steel production capacity is a painful process, and to encourage construction steel, to promote the residential steel structure can become an effective channel to divert steel capacity. China's annual new construction residential area is huge, which provides a broad platform for the steel development. The residential steel compared to the space steel, the heavy steel structure of the high-level design, construction, and technical requirements, so the pace of development will be faster, once the technology is forming, and will usher in the explosive growth. Currently, however, there are many factors that constrained the development of China's steel residential.
Residential steel in the design, construction, and materials with traditional concrete building has been completely different, the promotion of residential steel, whether from the concept, or from a technical perspective is leaps and bounds subversive of traditional architectural forms. Real estate companies in China in recent years has a higher profit margin, highly leveraged operations, the developers do not want to take the plunge to new architectural forms.
Although the steel structure technology has matured, but due to the lack of industrial conditions, wall materials, stone coated metal roofing tiles,flooring, bathroom and other supporting materials technology is not mature, and therefore its industrialization, also need a lot of supporting work.
From the living customs of our people prefer to live in the houses of civil engineering structures, the use of the history of the country for the wide range of steel not last long. Therefore, China's steel industry can usher in the explosive growth, or suspense. If the country is not strong policies to promote residential steel in China will remain in the slowly evolving.
