In recent years, the technology of assembly steel structure building is rapidly advanced, and the building industrialization is gradually realized by the concept. Along with the development of society, the requirements of people on building space are gradually improved, modern fabricated steel structure technology must be advanced, the most basic use requirements of people are met, and the fabricated steel structure technology also has more excellent performance, so that the fabricated steel structure technology cannot be eliminated in the rapid development trend of modern technology.
At present, the use requirements of people on buildings are mainly embodied in that the space requirements on the structures of the buildings are larger, the structures need to have enough open space, and the requirements on attractiveness are met. This results in an increase in the height and span of the structure, and the structural columns, as vertical force-transmitting members, need to withstand greater axial forces in high-rise structures and large-span structures, thereby placing greater demands on the load-bearing capacity of the structural columns. While meeting the bearing capacity, the structure still has better performance such as anti-seismic performance, durability and the like. The performance of a structural column, which is a key stressed member of a structure, can often determine the performance of the entire structure. This requires that the columns not only meet the strength requirements for load-bearing capacity, but also have superior seismic performance. In general, increasing the cross section of the columns, increasing the number of columns, and the like can improve the load-bearing capacity and seismic performance of the columns. However, the increase of the column section enables the bearing capacity to be improved, and meanwhile, the column occupies a larger space, and the huge column can not meet the requirement of space saving and the requirement of attractive appearance. The increased number of columns, while increasing the load carrying capacity, also has the problem of wasted space and poor integrity.
With the development of technology, in order to solve the above-mentioned existing disadvantages, a concept of a composite column has been proposed. The combination column has higher bearing capacity and good ductility, and particularly, the steel tube concrete combination column remarkably improves the characteristic of poor ductility of concrete, particularly high-strength concrete, due to the continuous constraint action of a steel tube on the concrete. Although the existing combined column technology and the steel pipe concrete combined column technology have great technical improvement compared with a single column, the following defects still exist: 1. the installation process is complex, the assembly degree is low, and the construction period is long; 2. the technical requirements on constructors are high, field welding is needed, and the quality is easily influenced by field construction; 3. the steel consumption is large, the technology is complex, and the construction cost is high; 4. the integrity is low, and the product is difficult to repair after being damaged; 5. poor flexibility and universality, difficult realization of the general applicability of the components in industrialized production, and the like.
