Experimental investigation into the structural performance of compressed high strength steel (HSS) square and rectangular hollow sections. Tensile coupon tests, measurements of geometric imperfections, full cross-section tensile tests and stub column tests. Assessment of the Eurocode 3 design guidelines for high strength steels. Assessment of material ductility requirements, the Class 3 slenderness limit for internal elements in compression and the effective width formula for Class 4 internal elements in compression. Reliability analysis of design recommendations.
