The development trend of steel frame structure is well known in recent years, especially in the application of high-rise residential buildings, and the capital construction of some large and medium-sized urban landmark buildings. In addition, it is the meaning of green buildings recognized by the construction industry.So what is the future market prospect of light steel structure construction in China?People have a brief analysis.

The way of light steel structure architecture comes from the early 90′s, which was introduced into China.Now steel structure manufacturers are everywhere, some companies with overall strength have developed and designed their own patented technology and light steel keel partition forming generator set.The key selection of the light steel structure roof is the arc arch management system. There are two ways: floor type and non floor type. Most of them choose the airtight roof without windows.

Light steel structure

According to the survey, the total construction area of light steel structure buildings, profiled plates that have been completed for a long time, and arch structures is about 2.5 million square meters, with an annual growth of more than 1 million square meters.Light steel structure building has good economic benefits. At present, it has a very broad development prospect in China.

At present, the key problem of arch roof steel frame structure is the overall stability and partial stability of arch shell.Because the internal force distribution and deformation characteristics of the arch shell are very sensitive to the shortcomings, after a lot of practical experience, although the cross-section improves part of the stability, it does great harm to the overall imbalance.In addition, the arch foot force also clearly puts forward higher regulations for the substructure, and the interaction between the arch roof and the substructure also does great harm to the stability of the arch. Therefore, the basic theory of design conception, analysis and calculation of the arch roof structure needs further improvement and scientific research
