Pro 20 STR — 3" Leg Track Section Properties
— Pro 20 STR Physical & Structural Properties
Notes: • Section properties were determined in accordance with AISI-NASPEC 2001 w/2004 Supplement
• Effective Properties are conservatively based upon basic C-section; Improved values are possible by applying the AISI Direct Strength Method.
• Effective Properties and moment capacity did not incorporate stress increase as a result of cold work of forming.
A
Calculated moment of inertia(Ixe) is based on serviceability determination.
B
Allowable bending moment is based on a fully braced section about it major axis.
* Web-depth to thickness ratio exceeds 200. Web stiffeners are required at all bearing locations, and no web holes are permitted.
** Web-depth to thickness ration exceeds 260. Web stiffeners are required at all bearing and intermediate locations, and no web holes are permitted.
