Steel structure building is environmental explore new direction

Introduction: architecture can be down to reconstruction. In a few decades, if steel structure house demolition of words, material can also be used to recycling. This will not cause too much secondary pollution, so from bearing system for steel structure in the future for a long time will lead the main structure of the system. Reporter: in the 2012 annual meeting of the architectural society of China at the BBS, vice President of Beijing university of technology ZhangAiLin is industrialization fabricated multi-layer steel structure system development published a wonderful speech. After the meeting, ZhangAiLin vice President accepted the sun building network interview.
Reporter: the sun and building some time ago in-depth a domestic real estate developers of scientific research base, understand their housing industrialization research situation. With your steel structure, compared to their housing industrialization in used in composite material more. For our country in residential development direction of industrialization, you think the steel structure of the outstanding advantage in where?
ZhangAiLin: steel structure of the main function is to solve the housing structure, their load problem, steel structure and can't solve all problems. But steel structure because of its superior function, it solved the skeleton later, it will be the other space province out, maintenance system, partition, interior or exterior wall or can dispense with the. But, also won't because only use steel structure, we will be able to set up the house, that's for sure. So someone says the next building age is steel structure of The Times, I don't agree with this view.
Steel structure building are not one hundred percent effective way to deal with, but the direction in the long run, some useful research and development reference. Especially in steel structure can tear open outfit attributes, architecture can be down to reconstruction. In a few decades, if steel structure house demolition of words, material can also be used to recycling. This will not cause too much secondary pollution, so from bearing system for steel structure in the future for a long time will lead the main structure of the system. That's for sure.
A second problem is that our country with an average annual seven hundred million tons consumption, the consumption in what place? And our country now is the lack of iron and steel. Today I still have not said steel bridge, foreign whether highway bridge or railway bridge, and most of them are all steel. And we are now the vast number of bridge or reinforced concrete structure, these things after demolition, which causes the waste slag cement, stone processing where to go? This is a big test of environmental protection.
Reporter: you just said for the steel structure cost problem, I have added part. Now the industrialized production house price is very high, because it is a lot of new materials is very expensive. This it can be seen that cost is a very complicated problem, not single with the steel structure.
ZhangAiLin: here I want to emphasize that the residential building cost. What is the cost? The house cost is according to the supply and demand of the decision, any goods, more than houses, with marxism explained that is, the price is decided by the market. But the market is decided by the contradiction between supply and demand, if our housing supply exceeds demand, the price will sell so high? Now the house in addition to Beijing, Shanghai, general provinces city center, lots of houses are in every square metre twenty thousand, at least not less than ten thousand. The cost of the house by land, fabrication cost and other composition. The cost of steel structure and reinforced concrete about, even steel structure cost than the general  Steel structure building of every square metre is more than five hundred, or even two thousand, in twenty thousand the price, and it accounts for how many? The most high-end fine decoration it is said that more than two thousand per square meter, and the prices of? Say so, house prices and the structure and decoration are not too big relations.
