Video Shows Seismic Brace in Action
Posted by Tom Klemens on February 15, 2011 at 9:56 AM.

scorpion_ybs1.jpgA recent Discovery Channel program showed Cast Connex’s Scorpion yielding brace system being tested at the University of Toronto. In addition to showing the 40-second test, the short segment also does a good job of explains the benefits of seismic bracing and includes conversations with several of the people involved in the Scorpion’s development and testing.

Galvanizing Tips
Posted by Lauren DiPalma on February 14, 2011 at 9:43 AM.

ld.jpgHot-dip galvanizing provides corrosion protection for steel without altering the material properties (there are some exceptions for very high strength steel). Galvanizing is frequently used for exterior steel and steel in corrosive environments. The following link from Duncan Galvanizing includes some useful tips www.duncangalvanizing.com.

Steel Shots: Super Bowl XLV
Posted by Alison Trost on February 4, 2011 at 9:25 AM.

Steel from the old Dallas Cowboys stadium in North Texas was melted down at Gerdau Ameristeel’s mini-mill in Midlothian, Texas to create the 16-ft high, 7-ton monument seen above. This structure is on display in the heart of Sundance Square for Sunday’s big game - Super Bowl XLV - where the Green Bay Packers will take on the Pittsburgh Steelers. For more information about the steel sculpture, visit the ESPN website by clicking here. Photo: Karen Campbell.

 

This Sunday, the Packers and the Steelers will play for the coveted Super Bowl champion rings. But have you ever wondered how the Steelers came to be the Steelers? Or where that logo came from? Here’s a brief history, and recognition for how great steel really is!

 

Art Rooney founded Pittsburgh’s football club in 1933, naming the team the Pittsburgh Pirates, which since 1890 had also been the name of the city’s baseball team. He changed the football team’s name in 1940 to the Pittsburgh Steelers to reflect the area’s heritage.

 

In 1962, Republic Steel of Cleveland approached the Steelers and suggested that they consider the Steelmark, the insignia used by the American Iron and Steel Institute (AISI), as a helmet logo to honor Pittsburgh’s steel heritage. The Steelmark logo, a circle enclosing three hypocycloids (diamonds with inward-curving edges) and the word STEEL, was created by United States Steel Corporation (for a time known as USX Corp. but now back to U. S. Steel ) to educate consumers about the importance of steel in their daily lives.

 

According to AISI, the three hypocycloids in the Steelers’ logo represent “the three materials used to produce steel: yellow for coal; orange for iron ore; and blue for steel scrap.”

 

For more detailed information about the Steelers logo and its origins, visit the team website by clicking here or the American Iron and Steel Institute by clicking here

Building the Bayonne Bridge’s Upper Deck
Posted by Tasha Weiss on February 3, 2011 at 9:27 AM.

Recognized by AISC as the most beautiful steel bridge in its class in 1931, the Bayonne Bridge connecting Staten Island, N.Y., with Bayonne, N.J., is poised for a serious makeover.

 

Officials have released additional information about the proposed $1 billion Bayonne Bridge project which will replace the existing roadway with a new deck about 60 feet higher up the arches to allow taller ships to pass.

 

The New Jersey On-line website www.nj.com reports the project is envisioned as “a widening of the four traffic lanes from 10 to 12 feet each, along with the addition of shoulders, and a center divider that will replace what is now just a double-yellow line.”

 

The report also shares comments from Peter Zipf, chief engineer for the Port Authority of New York and New Jersey, describing one possible approach to the challenging construction. “The two inner lanes will be closed to traffic and used as a staging area where a crane will likely be used to hoist a series of 84-ft-wide girders into place, forming the steel structure underpinning the new roadway. Like the original, the new roadbed will be suspended by steel cables from the bridge’s original 79-year-old arch. The two existing outer lanes will remain open, shielded from the work overhead, providing one traffic lane in each direction. To rise to the level of the higher roadbed, the bridge approaches will be made slightly steeper and longer, constructed in a similar method from staging areas on the original approaches.” To read more, click here.

 

Be sure to click on the diagram to see a larger image of how the new, higher roadway will run through the existing arch.
