Characteristic analysis of steel structure
Structures made mainly of steel are one of the primary types of building structures. The characteristics of steel are high strength, light weight and high rigidity, so it is particularly suitable for creating large-span and super-high and super-heavy buildings.
The material has good homogeneity and isotropy, is an aspirational elastomer, and is most suitable for the foundation assumption of general engineering mechanics; the material has good plasticity and toughness, can have large deformation, and can withstand excellent dynamic loads; the construction period is short; its industrialization It has a high degree and can be produced professionally with a high degree of mechanization.
High processing accuracy, high efficiency and good airtightness, so it can be used to create gas tanks, oil tanks and transformers. The disadvantage is poor fire resistance and corrosion resistance. It is mainly used for load-bearing skeleton of heavy workshop, workshop structure under dynamic load, plate and shell structure, upright TV tower and mast structure, bridge and warehouse and other large-span structures, high-rise and super high-rise buildings, etc.
In the future, the steel structure should study high-strength steel to greatly increase its yield point strength; in addition, new types of steel, such as H-shaped steel (also known as wide-flange steel), T-shaped steel, and profiled steel plates, should be rolled to adopt large-span structures And super high-rise buildings.
Steel structure is divided into light steel and heavy steel. It is judged that there is no common standard, and many experienced designers or project managers often cannot fully understand, and can be considered and judged with some data.
