Research on The Force Analysis and Application of Slender Stainless Steel Column Sections

Stainless steel, as a green building material, has many advantages, including aesthetically pleasing shapes, good corrosion resistance, stable mechanical properties, long service life, low cost, and easy maintenance. It is often used in structural construction, such as buildings and infrastructure. One of the typical cross-sectional forms of stainless steel used in construction is the slender stainless steel section. Slender stainless steel columns have high strength, which is consistent with the high material hardness and obvious stress hardening characteristics of stainless steel. Therefore, they are widely used in stainless steel components. Stainless steel has a non-linear stress-strain relationship, and among them, open slender cross-section stainless steel members are more prone to developing local and distortion section instability, so these members have complex non-linear instability behavior. This paper reviews the current status and future prospects of the force analysis and application research of slender stainless steel column sections. This paper analyzes the bending load-bearing capacity and stability analysis results of stainless steel materials using finite element models by several different teams, and compares the advantages and disadvantages of the effective width method and direct strength method in section calculation. Finally, the application route of slender stainless steel column is analyzed, and the application prospect in people's production and life in the future is put forward.
