Steel Construction

In the steel structure more than 200 years history, its constructionstyle along with society's development,the values'change and the esthetic appeal variation, the technology and arts passes throughout.This article embarks on the steelmaterial behavior and draws the conclusion of steel structure modeling rule through massive examples'analysis. At the same time the steel structure modeling basic principle is proposed. When the structure shaping is involved, the essay discusses its modeling potential using the new unique angle of view.Lacks the detail research and the design always is the soft rib in our country since long ago. The article inspects the intrinsic logic of node structure by the tectonic concept, moreover, this concept frame not only transplants the western constitution theory in geography , but provides the close between blind ditch of the traditional construction and the Chinese modern architecture in time, and strengthens the esthetic continuity , so that the new possibility for steel structure's localization is provided. Outside the ecology significance, this research also has the possibility of cultural science explanation. It's aim.
