Introduction to building steel structure

building steel structureIt is a structure composed of steel and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other parts made of section steel and steel plates, and adopts silanization, pure manganese phosphating, cleaning and drying, galvanizing and other anti-rust and anti-rust processes. Components or parts are usually connected by welding, bolts or rivets. Duebuilding steel structureLight weight and simple structure, so it is widely used in large factories, stadiums, high-rise buildings and other fields. Steel structure is easy to rust. Generally, steel structures need to be derusted, galvanized or painted, and require regular maintenance.

The characteristics of steel are high strength, light weight, good overall rigidity and strong deformation resistance. Therefore, it is particularly suitable for the construction of large-span and overweight buildings. The material has good uniformity and isotropy, and is an ideal choice for elasticity.building steel structureIt conforms to the basic assumption of general engineering mechanics, has good plasticity and toughness, can deform greatly, and can bear dynamic load well.

Steel structure should study high strength steel to greatly improve its yield point strength. In addition, new types of steel should be rolled, e.g.H-beam (also called wide flange steel),T-beam and profile steel plates to meet the needs of large-span structures and high-rise buildings.

In addition, there is no thermal bridgebuilding steel structuresystem. The building itself is not energy efficient. This technology uses clever special connectors to solve the problem of hot and cold bridges in buildings. The small truss structure allows cables and water pipes to pass through the wall. Convenient decoration. The following to introducebuilding steel structurecharacteristics.

1,High material strength, light weight

Steel has high strength and high modulus of elasticity. The ratio of density to yield strength is relatively low compared to concrete and wood. Therefore, under the same stress conditions, the steel structure has a small cross-section, light weight, easy transportation and installation, and is suitable for large-span, high-height and heavy-duty structures.

2,Steel toughness, good plasticity, uniform material, high structural reliability

building steel structureIt is suitable for bearing impact and dynamic load, and has good seismic performance. The internal structure of steel is uniform, close to isotropic homogeneous body.building steel structureThe actual working performance is more in line with the calculation theory. Therefore, the steel structure has high reliability.
