Abstract: Based on the stability demand of steel columns under axial compressive loads, the relation of axial load N and the calculation length lo is worked out according to the code for design: steel structures. In the chapter of N-/o, we can find the proper section that can satisfy the stability and rigidity demand. It can be reference for design and research.

Keywords: section steel; axial load; simplified method
