The characteristics of steel are high strength, light weight, good overall stiffness, and strong resistance to deformation, so it is especially suitable for the construction of large-span, super-high, and super-heavy buildings; the material has good homogeneity and isotropy, and is ideal elasticity. It is in line with the basic assumptions of general engineering mechanics; the material has good plasticity and toughness, can have large deformation, and can withstand dynamic loads well; the construction period is short; its degree of industrialization is high, and it can be used for specialized production with a high degree of mechanization.
Characteristics of steel structures
1. Steel toughness, good plasticity, uniform material and high structural reliability
It is suitable for bearing shock and dynamic load, and has good seismic performance. The internal structure of steel is uniform, close to isotropic homogeneous body. The actual working performance of the steel structure is more in line with the calculation theory. Therefore, the reliability of the steel structure is high.
2. High material strength and light weight
Steel has high strength and high modulus of elasticity. Compared with concrete and wood, the ratio of its density to yield strength is relatively low, so under the same stress conditions, the steel structure has a small cross-section and light weight, which is convenient for transportation and installation, and is suitable for large spans, high heights, and heavy loads Structure.
3. High degree of mechanization of steel structure manufacturing and installation
Steel structural members are easy to manufacture in factories and assemble on site. The factory mechanized manufacturing of steel structural components has high precision, high production efficiency, fast assembly speed on site, and short construction period. Steel structure is the most industrialized structure.
