Advantage Steel Buildings

Steel construction, in recent years, has been more and more development, especially in China, but the development of steel for decades, but the use of steel structure is a great development, and the gradual application of the stand up.
Stadiums, museums, high-rise buildings, etc., are not used to build the steel structure, then what advantages can make a large number of steel structures are used, for the following reasons:
1, the use of materials to save light at this point above, compared with the use of stone and cement structures built like a lot of their own steel structure stability, combined with the building built into the decoration, very unique, not only removed Stone due to the volume of stone space occupied space.
2, a good ductility If the steel material for processing, to be extended, then you can build a higher level or a large building, which is the stone can not be compared. If the construction of a high-rise building, the cost of steel is more than stone or more, then the answer is no doubt.
3, seismic strong steel structure of the building, at least to the anti-7 or so of the earthquake, which is basic, but if it is like stone, usually in about 5 will start cracking, and the shock of falling stones easily hurt To the people, and steel is not the same, so this is above the stone can not be compared.
The above advantages, you can see why the steel structure can flourish, if the steel structure as a "system", then its compatibility and security, it is very good.
