Steel structure buildings have the following characteristics:
Material has high strength and light weight: Steel has high strength and high elastic modulus, which makes the steel structure components small in cross-section and light in weight, making them easy to transport and install. They are particularly suitable for structures with large spans, high heights, and heavy loads.
Good seismic resistance: The steel has good toughness, good plasticity, uniform material, high structural reliability, is suitable for bearing impact and dynamic loads, and has good seismic resistance.
High degree of mechanization in manufacturing and installation: Steel structure components are easy to manufacture in factories, can be assembled quickly on site, have high production efficiency and short construction period, and are the most industrialized structural form.
Good sealing performance: The welded structure can be completely sealed and is suitable for containers and pipelines that require high-pressure sealing.
Poor heat resistance: When the temperature exceeds 150°C, the properties of steel will change and thermal insulation materials will be needed for protection. At 300℃-400℃, the strength of steel decreases significantly, and at 600℃ the strength approaches zero, so special fire prevention measures are required.
Poor corrosion resistance: It is easy to rust in humid and corrosive environments and requires regular maintenance and anti-rust treatment.
Environmentally friendly and reusable: Steel structure buildings can greatly reduce construction waste, and the components can be reused, meeting the requirements of green buildings.
