Designing With Structural Tubing - AISC
www.aisc.orgSteel design specifications were pri marily developed from experience with hot-rolled sections and it was not until the late 1940s that criteria for circular tubes appeared in U.S. design specifications. Technology for efficiently mass producing square and rectangular structural tubes has developed in the past few decades, generating

web2.clarkson.eduIf the flow is laminar, a result similar to that for circular tubes is available for the friction factor, which can be written as . f C= / Re , where . C. is a constant that depends on the aspect ratio . ab / , and the Reynolds number is defined using the equivalent diameter. values of …
