Buckling of Fixed-ended Concrete-filled Steel Columns ...

In recent years, due to a relatively high price increase of nickel alloys, there is an increase in demand for lean duplex stainless steel (LDSS) with a low nickel content of ~1.5%, such as grade EN 1.4162. LDSS offers roughly twice the strength compared to austenitic stainless steels and has great potential for expanding future structural possibilities, enabling a reduction in the section ...

The local buckling behaviour of steel plates in CFST columns is characterized by the outward buckling mode. Ge and Usami [5] performed nonlinear finite element analyses on short thin-walled CFST columns and proposed ultimate strength formula for steel plates in uniform compression. Wright [6] derived the limiting width-to-thickness ratios for proportioning steel plates in contact with concrete.
