Hirschfeld President Richard Phillips Joins AISC Board
Posted by Alison Trost on September 1, 2010 at 10:08 AM
Phillips initially joined Hirschfeld in 2004 as chief financial officer and was named president in 2008. As such he is responsible for the management of all operating divisions for the company, which is one of the largest fabricators of steel bridges, structural, industrial and nuclear projects in North America. Phillips also serves as CEO of Martifer-Hirschfeld Energy Systems, a partnership with Oliveira de Frades, Portugal-based Martifer Group to manufacture state-of-the-art wind tower systems, where he manages North American operations and supervising wind tower design, production and shipping.

2010 Code of Standard Practice Now Available
Posted by Tom Klemens on August 30, 2010 at 8:51 AM The 2010 Code of Standard Practice for Steel Buildings and Bridges (AISC 303-10) is now available. The PDF version can downloaded for free at www.aisc.org/freepubs.
The COSP, which is updated every five years, provides all involved in the design, purchase, fabrication and erection of structural steel with a current and useful framework for a common understanding of acceptable standards when contracting for structural steel.
Some of the most significant changes in this edition of the Code have to do with options for delegating connection design. Click here to read more on the AISC website about what’s new in the 2010 COSP. |

What's being answered right now:
Q.
Is it okay to substitute all thread rods for anchor bolts as long as we maintain correct length and tack weld bottom nut?
A.
AISC does not address welding of nuts, as this can often have a detrimental effect on the load carrying capacity of the nut. Many engineers will do this, feeling it has little consequence when done on the unstressed end of the rod; however, this is an engineering judgment call. Others will require the use of thread locker or to damage the threads as an alternative.
Whether you choose to use a fully threaded rod or not may depend on the design parameters of the base anchorage. The tensile capacity of the rod material itself will be based on the net tensile stress area of the rod, even if the AISC allowable design stress is stated in terms of the nominal area. This allowable stress has been factored to account for the reduction in area due to the thread. If for some reason, elongation of the anchor is a concern with the base detail used, you will want to make sure that you take the properties of the rod into account. |
