Steel construction: expansion of the quake zone happiness space
Our compatriots lost their loved ones, China earth sad bells ringing. After Wenchuan, Ya'an, Yushu, Minxian, every cause endless harm to our fellow earthquake, even a good seismic performance shelters are pitiful, citizens in a time of disaster aftershocks shaking, panic. Earthquake insiders often say: "Murder is not an earthquake, but the construction." According to the data, the earthquake in more than 95 percent of casualties are caused by the collapse of the house.
"The vast majority of the victims are crushed by collapsing house." "Most houses were razed to the ground." "Difficult to see the construction of a village after the earthquake." ...... Such rhetoric has become the most commonly used media statement, each construction also deeply hurt the heart. As a construction man, we should clearly recognize those fallen reinforced brick house is not without life, but in the New Year, no matter how far back should be eating a dinner of local, but also to protect our loved ones a happy peaceful life in space, those houses there is a cozy name - home.
It is built to join the cause we built this space were all happy, we have a responsibility to help disaster reconstruction work carried out for the disaster to build safer houses, while the strong earthquake in Foshan Steel residence is we accomplish this mission breakthrough. Seismic difference is the soft underbelly of the civil house, while the seismic performance of steel construction has a strong enough. Steel is elastic seismic, steel tensile, compressive, shear, bending can be more substantial, is an excellent material ductility, steel frame of steel columns and pile choose just elasticity of convergence, but also by the entire steel skeleton just elastic integral convergence, stability, scalability far exceeds civil. When a strong earthquake energy, able to rely on the elastic deformation of steel to digest strong force, softness, more theoretically 8 earthquake will not be allowed to collapse, very suitable for the construction of multi-shock region. People want to take up the burden of Steel construction steel shelter, Yusaku implementation steel residence pioneer.
Reference resources, able to attack Jade
In China, Foshan, mostly concentrated in the construction of high-rise steel construction, convention centers, stadiums, etc., steel shelter still in the initial period, the less the patented technology, far less than the level of industrialization, from a global perspective, the steel in many countries Let's residence development model structure worthy to learn from. Japan is in the Pacific seismic belt, earthquakes often occur, more than six earthquakes occur each year worldwide, fifth place in Japan. However, each year up to a thousand times felt earthquakes in Japan rarely massive house collapsed because Japan attaches particular importance residence good shock resistance. Back in the late 1990s, the Japanese steel prefabricated dwellings will account for 71 percent, specializing in steel companies produced about ten homes. A number of countries the United States, France, Finland, Australia and other home systems have proven steel, steel live a considerable share of the market.
Currently, developed from dedicated systems to large-scale industrialization general system, namely the development of standardization, serialization, universal construction of components and parts, building parts for the center, professional, social production and commercialization of supply for the basic direction residence industrial modernization model, its main support is steel. In China, only 5% steel construction, steel shelter and even fewer, broad space for development, major development sense, we should be confident of Steel people.
Steel shelter, long way to go
The State Council issued the "serious excess capacity on resolving conflicting guidance" clearly states: the steel industry to be implemented in the field of steel used in construction, public construction and government to improve the proportion of construction using steel sector investment in earthquake-prone areas and other natural disasters implementation of integrated light steel houses, such as seismic-type construction. Steel construction is an important representative of green building, the State Council in the implementation of lightweight steel house seismic belt policy to bring endless steel shelter space for development, but also for the company to bring new development opportunities.
Due to the economic and technical conditions in the history of the limit "undefended countryside, high-risk urban" has become status quo seismic zone, each earthquake disaster, we are prompted, how effective processor utilization to reduce future earthquake infinite potential human-caused catastrophe. The task in this large Chinese population, the project needs to be improved seismic capacity of the local area, in particular, need a good reflection, how can we truly ensure the safety of life and property of the State and citizens, one thing can be clearly yes, steel shelter long way to go. Faced with an earthquake, as the steel people, should turn grief as the driving force to study how developed specifically with the construction of steel structures for earthquake shelter, to think about how to optimize the steel reasonable accommodation, to explore how to implement steel shelter, so steel shelter The concept is known society, and lay a solid foundation for the steel shelter industrialization.
