corner cracking cold formed rectangular hss

  • Structural Efficiencies Hollow Structural Sections

    Cracking in the corners of cold formed, square and rectangular hollow structural sections (HSS) has been reported and discussed for some time. In the last decade the incidence has increased in North America and Asia, particularly during hot dip galvanizing, where the problem has been generally attributed to Liquid Metal Embrittlement (LME) in association with very high residual stresses in the cold formed HSS corners.Read More

  • Hot Dip Galvanized Hollow Structural Sections Crack

    In an even worse case, if such cracks do not cause visible damage to the section and remain undetected before the final product leaves the galvanizing shop, they can result in serious consequences on the performance of the structure. This research aims to investigate the conditions which lead to cracking of hot dip galvanized cold formed HSS.Read More

  • Welding Hollow Structural Sections

    HSS are manufactured in North America by cold forming and the corner radii are intentionally fairly large to limit the loss of ductility and toughness in the corner regions, promote weldability and to address potential corner cracking. ASTM A500 10 permits an outside corner radius of up to 3tnomRead More

  • ADVANCES IN HIGH STRENGTH STRUCTURAL STEEL

  • Charpy V notch impact toughness of cold formed

    The modern design of structures made of cold formed hollow structural sections (HSS) and their welded joints is largely dependent on the redistribution of stress in the inelastic range. Thus, the selection of HSS for CVN toughness is critical if low temperature or dynamic loading is a design consideration.Read More

    RHS Corner Behavior under Seismic Loading Cold formed square hollow sections have a real Fy / Fu ratio which is sometimes very high (0.85 to 0.95), even in the flats, and square hollow sections are prone to fracture in the corners after local buckling, even with low b/t ratiosRead More

  • ADVANCES IN HIGH STRENGTH STRUCTURAL STEEL

    highlighted problems regarding surface finish and corner cracking with certain cold formed square and rectangular hollow sections. Together with other studies such findings, for example, have led to a fundamental re appraisal of the cold formed manufacturing specification in North America.Read More

  • Charpy V notch impact toughness of cold formed rectangular

    The Charpy V notch (CVN) impact toughness of cold formed rectangular hollow sections (RHSs) of different cross sectional geometries and produced by different methods (direct forming, continuous forming, and continuous forming plus heat treatment) has been investigated comprehensively in this study. It can be concluded from this work that(1)Read More
