Advantages of rapid development of steel structure

Hits：1503 Time：2017-4-1
　　In recent years, the rapid development of steel structure, the state of the steel structure analysis of the development of the rapid development of the reasons: the advantages of their own. What are the advantages of the steel structure?
钢结构
(1) high strength steel
Compared with steel and concrete, the yield point of steel is much higher than that of concrete and wood, although the bulk density is larger than that of concrete. Under the condition of the same bearing capacity, compared with the reinforced concrete structure, the steel structure is smaller, lighter and easier to transport and install. Therefore, especially suitable for large span, height and weight bearing structure, also suitable for mobile, easy to dismantle the structure.
(2) the steel structure is safe and reliable
The material is homogeneous, isotropic, elastic modulus, good plasticity and toughness, and it is an ideal elastic-plastic body, which is consistent with the current calculation methods and basic concepts. Therefore, the steel structure has the advantages of high accuracy and high reliability, and is suitable for buildings with special significance.
(3) high degree of industrialization of steel structure
Although the production of steel structure requires complex mechanical equipment and strict process requirements, but compared with other building structures, the steel structure of a high degree of industrialization, with the production of large quantities and high degree of accuracy characteristics. Can be used factory manufacturing, site installation of construction methods, shorten the construction cycle. In order to reduce costs, improve efficiency and create conditions. (4) good sealing property of steel structure
Because the welding structure can be completely sealed, pressure vessel, some requirements of air tightness and water tightness good, large oil gas pipelines and other shell structures are suitable for steel structures.
(5) the steel structure has a certain heat resistance
When the temperature is below 250 DEG C, the quality of the steel is very small, the temperature reaches to the temperature of 300 DEG C, and the strength decreases gradually. When the temperature reaches the temperature of ~650 DEG C at 450 DEG C, the strength is reduced to zero. Therefore, the steel structure can be used for the temperature is not higher than 150 degrees.
