What is steel structure

The characteristics of steel are high strength, light weight, good overall stiffness, and strong resistance to deformation, so it is especially suitable for building large-span, ultra-high, and super-heavy buildings; the material has good homogeneity and isotropy, and is ideal elasticity. It conforms to 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.

Application of steel structure

roof system It is composed of roof trusses, structural OSB panels, waterproof layers, light roof tiles (metal or asphalt shingles) and related connectors. The roof of the light steel structure of Meite Building can have various combinations in appearance. There are also many kinds of materials. Under the premise of ensuring the waterproof technology, there are many options for appearance.

Features of steel structure

1. 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. 2. 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. 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 a kind of structure with a high degree of industrialization.

Reinforcing measures for steel structures

When the steel structure is damaged, we need to find and solve the problem immediately. The main factors for the damage to the steel structure are: 1) Insufficient bearing capacity of the structure caused by load changes, extended service, and changes in codes and regulations; 2) The components are deformed, twisted, disabled, dented, etc. due to various accidents, resulting in weakened sections of components, warped rods, and cracked connections; 3) Deformation, cracking and warping of components or connections caused by temperature difference; 4) The cross-section of steel structural members is weakened due to corrosion caused by chemical corrosion and electrochemical corrosion; 5) Others include mistakes in design, production, construction, and illegal use and operation during the service period. There are mainly three types of reinforcement technical measures for steel structures: 1) Cross-section reinforcement method: Reinforce with steel in part or along the whole length of the member, and connect them into a whole to make them bear common force; 2) Change the calculation diagram: add additional supports, adjust the load distribution, reduce the level of internal force, force the displacement of the statically indeterminate structural supports, and reduce the stress peak; 3) Prestressed cable method: use high-strength cables to reinforce weak links in the structure or improve the overall bearing capacity, stiffness and stability of the structure.
