It is a structure mainly made of steel. It is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates. Each component or part is usually connected by welds, bolts or rivets. It is one of the main types of building structures. Because of its light deadweight and simple construction, it is widely used in large factories, bridges, stadiums, super high-rise buildings and other fields.
Although China had outstanding achievements in iron structure in the early years, due to the constraints of the feudal system of more than 2000 years, science was underdeveloped, so it stayed at the level of iron buildings for a long time. It was not until the end of the 19th century that China began to adopt modern steel structures. After the founding of the People's Republic of China, the application of steel structures has made great progress, both in quantity and quality are far more than in the past. We have reached a high level in design, manufacturing and installation technology, mastered the design and construction technology of various complex buildings, and built many large-scale and complex steel structure plants, long-span steel structure civil buildings and railway bridges throughout the country, The three hinged steel arch of Shaanxi Qinshihuang Soldiers, Horses and Maids Exhibition Hall and the Bird's Nest in Beijing.
characteristic:
1. The dead weight of steel structure is light;
2. The reliability of steel structure is high;
3. The steel has good vibration (shock) resistance and impact resistance;
4. The industrialization degree of steel structure manufacturing is high;
5. Steel structure can be assembled accurately and quickly;
6. Large indoor space of steel structure;
7. It is easy to be made into a sealed structure;
8. Steel structure is easily corroded;
9. The fire resistance of steel structure is poor.
In recent years, the application of steel structure in construction engineering is more and more extensive, and has achieved very good application results. However, in the actual application process, there are also reasons The design work of is not in place, resulting in the problem of insufficient stability of the steel structure building, which seriously affects the safety of users' lives and property. In order to ensure that the construction of building steel structure engineering has a higher quality, it is necessary to design the steel structure engineering in strict accordance with the corresponding specifications and standards, and do a good job of the corresponding design points, so as to provide users with more safe and reliable steel structure buildings.
