What are the characteristics of steel structure applications?
Briefly describe the main characteristics of steel structures
1. High material strength and light weight
Steel has high strength and high modulus of elasticity. Compared with concrete and wood, its ratio of density to yield strength is low, so under the same stress conditions, the steel structure has a small section, light weight, easy transportation and installation, and is suitable for large-span, high-height, and heavy-duty structures.
2. The steel has good 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 and close to an 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
Structural steel members are easily factory fabricated and assembled on site. The factory-made mechanized manufacturing of steel structural components has high precision, high production efficiency, fast on-site assembly speed and short construction period. Steel structure is a highly industrialized structure.
4. Good sealing performance of steel structure
Since the welded structure can be completely sealed, it can be made into high-pressure containers, large oil pools, pressure pipes, etc. with good air-tightness and water-tightness.
Application of steel structure
1. Roof system
The roof system consists of roof trusses, structural OSB panels, waterproof layers, lightweight roof tiles (metal or asphalt shingles) and related connectors. Light steel structure roofs can have a variety of combinations in appearance, and there are many types of materials. Under the premise of guaranteeing waterproof technology, there are various options for appearance.
2. Wall structure
The wall of the light steel structure house is mainly composed of wall frame columns, wall top beams, wall bottom beams, wall supports, wall panels and connectors. Light steel structure houses generally use the inner transverse wall as the load-bearing wall of the structure, the wall columns are C-type light steel components, and the wall thickness is determined according to the load. The wall structure of the light steel structure house can effectively bear and reliably transmit the vertical load, and the layout is convenient.
