This work on thin unequal-leg angle steel columns continues the research aiming to develop design equations in the Eurocodes for important, yet more specialised, structural components where several structural phenomena interact: compression, bending and twisting.
18 Oct 2025
Our paper on the behaviour and design of unequal-leg stainless steel angle columns has been published. Work led by our excellent PhD student @rickydairk and co-supervised by @LeroyGardner10.

This work on flanged cruciform cross-section steel columns continues the research aiming to refine design equations in the Eurocodes for important, yet more specialised, structural components where more several structural phenomena interact: compression, bending and twisting.

One of my PhD students supervised with @LeroyGardner10 (star of @SkyNews on Tuesday) has just submitted his thesis with approx 3 hours to spare. We received his 1st 2 of 7 chapters on 12 March and turned the whole thesis around in 17 days, a task that usually takes months. 😅

A great pleasure to present once again at #EMI2023, a particular delight to present joint work on the complex topic of the buckling and design of steel angle columns with @BBehzadiSofiani and @LeroyGardner10.
Many thanks to my old mate @nbkaye for taking the photo.
