The tolerance of steel column installation verticality I
The deviation of the verticality of the steel column exceeds the value allowed by the design or specification. The reasons are as follows:
Steel column is not made to take control deformation measures, or there is bending deformation without straightening.
Or because the hoisting process and the hoisting roof panel program are unreasonable, the bending and deformation is caused by the action of temperature, wind and external force.
Or the span of the truss has a deviation, and the external force is forcibly connected during installation, which causes the verticality of the steel column to be excessively biased.
As a result, the steel column is biased when subjected to force, which affects bearing capacity and stability.
