The column support of steel structure is a connecting rod set between two adjacent columns to ensure the overall stability of the building structure, improve the lateral stiffness and transfer the longitudinal and horizontal force.Its main function has the following several aspects:
High structural stability
In high-rise buildings, columns with large height and small section area are prone to buckling instability.The support between columns can avoid the instability of the column and ensure the stability of the structure by increasing the stability coefficient of the column.
The seismic ability
In the event of an earthquake, pillars are prone to bend, twist and other deformations, which lead to structural damage.The support between columns can limit the deformation of columns, reduce the damage degree of the structure, and improve the seismic ability.
Optimal bearing capacity
In some long-span structures, the supporting columns are prone to pressure concentration and have poor bearing capacity.However, the support between columns can evenly distribute the force to each support point and improve the bearing capacity of the support point.
