How much steel construction, marking an economic power and economy of a country or region's level of development. After entering 2000, a significant increase of the national economy, national strength steel, steel production has become a world power, proposed to "positive, rational steel" in the building, from the get rid of the "limit of steel" bondage, steel buildings in the economically developed areas gradually increased. Strength Index by the elastic limit of steel σe, yield strength σy, and ultimate tensile σu, designed to yield strength of steel, based on the high yield strength steel can reduce the weight of the plant structure, save steel, reduce the cost. Tensile strength steel that is destroyed before σu can withstand maximum stress steel plant, this time because of the structure of large plastic deformation and lose performance steel shed, but the structure of large deformation without breaking, to meet strong earthquake resistant structures requirements when. 'Σu / size σy value parameter can be seen as strength of steel reserves. Steel warehouse, steel, Guangxi Guangxi Galaxy Galaxy is provided by the metal structure Engineering Limited.
