1. Concept of steel structure building. No matter what kind of building, in the process of construction, it is necessary to support the weighing skeleton of the whole building quality, which is also known as the building structural system in architecture. The so-called steel structure building is to take steel as the main material of the building structure system, and the building built with this structure is steel structure building. In fact, this concept is corresponding to wooden structure building, concrete structure and brick structure building.
2. Development status of steel structure buildings. China's steel structure building began to rise from the 1980s, after the 1990s, with the support of the state, showing a trend of rapid development. In recent years, steel structures have been widely used in large architectural systems, such as factories and stadiums. Its development status is mainly reflected in the following aspects.
(1) Steel structure building began to realize localization. China's steel structure construction started late, in the early stage of development due to the limitations of technology, construction equipment and other aspects, can not fully realize the localization, so in the actual construction mostly adopted the mode of sino-foreign cooperation, built a number of representative buildings, such as Shanghai Jin MAO Tower. Since the mid-1990s, some construction enterprises in China began to independently research, develop and construct steel structure buildings with years of construction experience. Especially in recent years, there are more and more steel structure buildings with completely independent intellectual property rights, and the construction technology is becoming more and more mature.
(2) Steel structure buildings present a trend of rapid development. With the rapid development of economy in our country, to meet the requirements of the quality and time limit for a project of building more and more high, and steel structure building to meet the requirements, safety and reliability, time saving and convenient use, etc, are widely applied to all kinds of buildings, including commercial buildings, entertainment, civil construction and sports facilities construction and so on. In particular, the construction of sports facilities, the newly built stadiums and gymnasiums in China in recent years, without exception, have applied steel structure construction technology. In addition, the sudden rise of light steel structure building, expand the scope of application of steel structure building, at present, some small building engineering also began to apply steel structure building technology, achieved better results.
