I am searching for test methods and standards for compressive strength of circular hollow structural steel (hss). My research is about analysis of using CFRP to increase the compressive strength of corrosion-damaged CHS columns.
Good luck 🙂
CIDECT has carried out extensive work on tubular structures.
