Abstract
The behaviour of hot-rolled high-strength steel (HSS) tubular sections under combined compression and uniaxial
bending was investigated both experimentally and numerically. The experimental programme encompassed a series
of material coupon tests, initial geometric imperfection measurements, residual stress measurements and 12 tests on
stub columns subjected to uniaxial eccentric compression. Numerical models were developed and validated against
the experimental results. An extensive parametric study was then performed with the aim of generating further
structural performance data over a wider range of cross-section slendernesses, aspect ratios and applied eccentricities.
The results were utilised for an assessment of the applicability of relevant Eurocode provisions to HSS cross-sections
under combined loading. Conclusions regarding the applicability of Eurocode interaction curves to S460 and
S690 square and rectangular hollow sections are presented.
