The intercolumn support of steel structure is a joint bar set between two adjacent columns to ensure the overall stability of the building structure, improve the lateral stiffness and transfer the longitudinal horizontal force. Its main role has the following aspects:
High structural stability
In high-rise buildings, the column height is large, the section area is small, it is easy to appear buckling buckling phenomenon. By increasing the stability coefficient of columns, the column instability can be avoided and the stability of the structure can be ensured.
Strong earthquake resistance
When the earthquake occurs, the column is prone to bending, twisting and other deformation, which leads to the destruction of the structure. The inter-column support can limit the deformation of the column, reduce the damage degree of the structure, and improve the seismic ability.
Excellent carrying capacity
In some large-span structures, the supporting columns are vulnerable to pressure concentration and have poor bearing capacity. The inter-column support can distribute the force evenly to each support point and improve the bearing capacity of the support point.
