Directionality Increase for Fillet Welds to HSS

I am normally not a proponent of writing about code changes before they appear in black-and-white print. That being said, I’m breaking my rule in this article in the name of safety and education as this is a frequently posed question to our technical consultants.

Expert Reactions to the Directionality Increase for Fillet Welds to HSS

We sat down with Dr. Jeffrey Packer, a professor at the University of Toronto, to hear about his most recent research and get his thoughts on the directionality increase for fillet welds to HSS.

Learning Opportunities

A1065: Oversize HSS

In this free webinar sponsored by the Steel Tube Institute, we will explore ASTM A1065 material. We’ll discuss what it is, how it’s made, what testing is performed and how to get it. You’ll learn to identify the sizes available in A1065 and how to correctly design with it according to the AISC 360 Specification.

Code Update for CJP HSS Welds: Be Informed Before You Specify

Weld design isn’t exempt from the differences between wide-flange and hollow structural section (HSS) connection design. Unlike open sections where welding is possible on both sides of the flanges and web, the interior of HSS sections commonly used in building structures can’t be accessed.

Round HSS Essentials

Round hollow structural sections (HSS) are used in a plethora of applications from bridges to transmission towers and stadium roofs, or from handrails to posts. HSS are also used beyond structures. Get the details from an engineer’s point of view.

Steel Imports Down 19% Year to Date Through July 2020

Based on preliminary Census Bureau data, the American Iron and Steel Institute reported recently that the U.S. imported a total of 2,690,000 net tons (NT) of steel in July 2020, including 1,367,000 NT of finished steel (up 92% and 3.6% respectively vs. June final data).
