A summary of current codified circular hollow section (CHS) design methods is presented.
A dataset of 342 existing CHS compressive and bending experimental results has been collated.
The dataset covers structural steel, stainless steel and aluminium CHS.
A detailed outline of the process of extending the continuous strength method (CSM) to cover CHS is presented.
The dataset CSM resistance predictions are compared against the EN 1993-1-1, EN 1993-1-4 and 1999-1-1 capacity predictions.
