This creates a cognitive barrier, leads to confusion, and impacts the viability of some members.\u003c\/p\u003e\n\u003cp\u003eThis session investigates the Canadian design wall thickness requirement for ASTM A500 HSS using modern dimensional data from producer quality control records. The data, obtained from seven HSS producers in North America, is analyzed to compute bias factors and coefficients of variation for wall thickness, outer dimension(s), cross-sectional area, moments of inertia, radii of gyration, and section moduli. A first-order reliability method analysis is then performed for HSS members subjected to compression, tension, and bending. The results support an upward revision of the ASTM A500 HSS design wall thickness in Canada, from 0.90 to 0.93 times the nominal wall thickness.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEligibility for CEUs\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCEUs will be issued for this webinar to participants that meet the following criteria:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eParticipant must attend at least 75% of the webinar\u003c\/li\u003e\n\u003cli\u003eCEUs are only eligible for a participant with a 90% attention rating.
