Selected, extended paper from the SDSS 2019 special session ECCS/TC8 – Structural Stability Cable‐stayed columns offer several advantages among traditional solutions. Owing to the additional restraint given by the prestressed cables and cross‐arms, they can provide enhanced buckling resistance in comparison to conventional columns. They are also aesthetically appealing, combining a strong architectural effect with a top‐notch engineering solution. This paper presents a design approach for the stability design of prestressed cable‐stayed columns. This method is based on the well‐known Ayrton‐Perry format, combining first‐ and second‐order effects. The imperfection factors were calibrated on the basis of experimental results. This method is consistent with design rules for uniform columns in Eurocode 3 and is easy to apply.
