摘要

This paper compares the geometric and mechanical properties of square hollow sections manufacturedrnin NorthAmerica by direct forming and continuous forming production methods. Square 152×152mmrnsections, produced by direct forming, continuous cold forming, and also with the latter subsequently stressrelievedrnby heat treatment in accordance with Canadian standards, are the basis of the comparison.The mechanicalrnproperties compared are the overall compressive behaviour (via stub column tests), tensile behaviour and ductilityrnin the flats and corners (via tension coupon tests), and notch toughness in the flats and corners as a function ofrntest temperature (via CharpyV-notch impact tests). It is shown that direct-forming, or “folding”, generally leadsrnto more favourable mechanical performance than continuous-forming, for square/rectangular hollow sections.
