1. High strength and light weight: steel has high strength, so the members of steel structure have small cross-section and light weight, which is convenient for transportation and installation. This characteristic makes steel structure especially suitable for large span, high height and heavy load bearing structure.
2. Good plasticity and toughness: Steel has good plasticity and toughness, which can absorb a large amount of energy, thus showing good anti-seismic performance. When natural disasters such as earthquakes occur, steel structure buildings can better protect people's lives and properties.
3. Uniform material, high reliability: the internal organization of steel is uniform, close to isotropic homogeneous body, so its actual working performance is more in line with the calculation theory, high structural reliability.
4. High degree of industrialization: steel structure components can be mechanized and manufactured in factories with high precision and high production efficiency. At the site site, these components can be assembled quickly, greatly shortening the construction period. This highly industrialized production method is conducive to improving project quality and reducing construction cost.
