Steel structure is a structure mainly composed of steel materials and is one of the main types of building structures.
The structure is mainly composed of steel beams, steel columns, steel trusses, and other components made of steel sections and steel plates. The components or parts are usually connected by welds, bolts, or rivets. Due to its light weight and easy construction, it is widely used in large factories, venues, super high-rise buildings and other fields.
The characteristics of steel are high strength, light weight, good overall rigidity, and strong deformation ability, making it particularly suitable for constructing large-span, ultra high, and ultra heavy buildings; The material has good homogeneity and isotropy, and belongs to the ideal elastic body, which best conforms to the basic assumptions of general engineering mechanics; The material has good plasticity and toughness, can undergo significant deformation, and can withstand dynamic loads well; Short construction period; It has a high degree of industrialization and can carry out specialized production with a high degree of mechanization. High strength steel should be studied for steel structures to greatly improve their yield point strength; In addition, new types of steel sections need to be rolled, such as H-beams (also known as wide flange steel), T-beams, and profiled steel plates, to meet the needs of large-span structures and super high-rise buildings.
In addition, there is a non thermal bridge light steel structure system. The building itself is not energy-efficient, and this technology solves the problem of cold and hot bridges in buildings with clever special connectors; The small truss structure allows cables and plumbing pipes to pass through the wall, making construction and decoration convenient.
When the steel structure is also damaged, we need to detect and solve the problem immediately.
The main factors causing damage to steel structures are:
1. Insufficient structural bearing capacity due to load changes, expired service, and changes in specifications and regulations.
2. Due to various unexpected deformations, twists, damages, dents, etc., the cross-section of the component is weakened, the members are warped, and the connections are cracked.
3. Deformation, cracking, and warping of components or connections caused by temperature differences.
4) Corrosion caused by chemical substances and electrochemical corrosion weaken the cross-section of steel structural components.
5. Other factors include errors in design, production, and construction, as well as violations of usage and operation during service life.
There are three main reinforcement techniques for steel structures:
1. Section reinforcement method: Steel reinforcement is used locally or along the entire length of the component to connect it as a whole and exert joint force.
3. Change the calculation diagram: add additional supports, adjust load distribution, reduce internal force levels, force displacement of statically indeterminate structural supports, and reduce stress peaks.
3. Pre stressing cable method: using high-strength cables to reinforce weak links in the structure or improve the overall bearing capacity, stiffness, and stability of the structure.
For potential problems in steel structure engineering, it is important to take corresponding measures. In addition, it is also important to find high-quality steel manufacturers and process teams with guaranteed quality.

Finally, the construction of rigid structures should not be taken lightly. Reinforcement techniques should be added according to the construction requirements, and should not be taken lightly, as it may cause unnecessary losses.
