Conceptualizing your Next Parking Structure
Posted by Tasha Weiss on February 27, 2012 at 12:10 PM.
If you’re planning to attend the 2012 Parking Industry Exhibition (PIE), March 18-21 at the Hyatt Regency O’Hare in Chicago, don’t miss out on the session “Building Tomorrow’s Steel-Framed Parking Structures Today.” AISC Regional Engineer Monica Shripka will discuss how using structural steel framing can reduce costs, scheduling and maintenance for your next parking project. The session will be held on Wednesday, March 21, at 9 a.m.
You’ll learn how efficient steel framing, an ample supply of readily available steel and active competition among fabricators all contribute to rapid project delivery and low construction cost. Shripka will present case studies on the latest design methods that demonstrate how smaller structural steel members can improve lighting and security for garage users, as well as how modern coating systems and steel framing can simplify inspections and reduce life-cycle maintenance costs.
You can also stop by the AISC booth in the exhibit hall to pick up additional information and talk about steel solutions for your next parking project. For more information about the conference, visit www.parkingtoday.com/pie.
Steel Structure Trivia: The Unknown Sculpture
Posted by Tasha Weiss on February 24, 2012 at 10:59 AM.
Brace yourselves for MSC’s first Steel Structure Trivia question! This is one of more than 140 renditions of the AISC Steel Sculpture that have been erected on college and university campuses since it was originally developed by Duane Ellifritt in 1986. The question is: Where in the world is this one? (Keep reading to find out how to enter the contest and submit your answer!)
Once you become aware of something, you begin to see that same thing in places you never noticed it before. For example, the car you just bought, an interesting architectural element or perhaps…the AISC Steel Sculpture.
The original sculpture was developed by engineering professor Duane Ellifritt as a way to give his engineering students at the University of Florida hands-on exposure to structural steel components and connections. It was erected on the UF campus in 1986.
The idea caught on and since then at least 140 more have been erected. As is common with structural steel, each has its own individual characteristics, but all reflect the distinctive appearance of Ellifritt’s original sculpture. This one is located on a prominent engineering school’s campus.
How to Enter the Contest:
We at MSC are excited to launch our monthly Steel Structure Trivia contest by seeing how many of you can correctly identify the school where this sculpture is located! If you think you know, send your best guess by noon (CST) on Monday, February 27, to Tasha Weiss at email@example.com. At that time, we’ll reveal the sculpture’s location.
The first three people who supply the correct answer will receive an MSC-branded stainless steel back scratcher! You’ll need it to successfully tackle those pesky itches after the trivia pressure subsides. (And check out that telescoping action! Wow!) Its five-fingered curved design reaches from 7 in. to 20 3/4 in. in length.
Think you have what it takes to win? You can test your steel structure knowledge right here on our MSC website on the last Friday of each month, where a new photo showing only a detailed portion of a steel structure will be posted to the Steel in the News section as our weekly “Steel Shot.” Your challenge is to correctly answer the trivia question provided in the news post based on what you see in the photo. The next question will be posted at 10 a.m. (CST) on Friday, March 30.
We’ll help you out a little bit for your first challenge; to narrow down the answer you can view a collection of many of the steel sculpture photos on AISC Education’s Flickr and Facebook pages. (Additions and updates to these pages are always welcome. Send that information to AISC education specialist Maria Mnookin at firstname.lastname@example.org.)
The AISC Education web page also includes a link where you can view a list of universities that have received a donated sculpture, as well as download the Connections Teaching Toolkit, a free PDF file that includes plans for the above sculpture.
ANSWER: The steel sculpture is located at the Stevens Institute of Technology in Hoboken, N.J. You can view additional photos and maps of its location in our slideshow gallery at http://bit.ly/z6JcbW.
Congratulations to the winner of our first Steel Structure Trivia challenge, Christopher Cichon with Sargent & Lundy in Chicago! We received several guesses, but Chris was the only person to correctly identify the campus location of the sculpture. Great detective work, Chris!
Thank you to everyone who participated! Remember to check back here next month for the next trivia challenge.

Lowry Avenue Bridge Arches now Complete
Posted by Tasha Weiss on February 22, 2012 at 12:29 PM.
The final piece of the steel arches for Minneapolis’ Lowry Avenue Bridge was lowered into place last Wednesday, February 15. This 40-ft, 73,000-lb center “keystone” segment is one of 22 segments that make up the arches, with each segment weighing between 70,000 lbs and 130,000 lbs.
Due to open in late summer, the cable-stayed, tied-arch design relies on support from above and below the main span. The 1,575-ft replacement bridge is supported by two piers in the river, steel cables running through the bridge deck and 36 cables connecting the bridge’s main span to the 90-ft-high steel arches.
Some predict the new bridge will last for centuries if well-maintained, according to an article published in Finance & Commerce; Hennepin County Commissioner Mark Stenglein says it could stand as long as 500 years, with modern construction materials and techniques extending its life span.
To read the full article and view a photo slide show of the last section of the steel arches being lowered into place, go to http://bit.ly/wx9oO5. For additional information on the Lowry Avenue Bridge project, including construction updates, photos and videos, visit http://lowryavenuebridge.com.

Every now and then we discover a previously unknown (or forgotten) collection of steel-related documents from the past. Three such collections are now available at www.aisc.org/epubs in the “Ideas + Answers” section under “Project Solutions.”
Two of the collections are project case studies created by U.S. Steel and Bethlehem Steel in the 1960s, 70s, and 80s. You may not recognize the projects, but they do a great job demonstrating the versatility of structural steel in everyday structures. Plus, the next time you’re in Bloomington, Minn., near I-494 and the airport, you can amaze your friends by telling them that the Crowne Plaza was originally a Holiday Inn and it’s framed with staggered trusses!
The third collection consists of brochures produced for Prize Bridge Award winners since the 1920s. Many of these bridges are still in use today.

Steel erection is now complete up to the 62nd floor of 4 World Trade Center, planned to be the fourth tallest skyscraper envisioned for the WTC site. Back in December, DCM Erectors provided AISC Regional Engineer Jacinda Collins with a tour of one of the newest additions to the New York City skyline. These are some of her observations:
“4 WTC is the smallest of the skyscrapers at the WTC site, however, it contains a number of unique features. It has a concrete core and utilizes steel and composite outriggers, as well as belt trusses, at the mechanical floors of the structure. The column-free spans from the core to the perimeter are approximately 45 ft with web openings for mechanical, electrical, plumbing (MEP).
The 44th story is the belt truss level and has a lot going on including a lot of welding.
4 WTC also has a number of super columns and is designed to resist blast and progressive collapse. For erection, DCM created steel platforms for the ironworkers to work at higher levels. The 3-5 story platforms allow the working level to rise with the columns and not the decking.”
A journal paper from the World Academy of Science, Engineering and Technology explains the belt truss concept. You can read the PDF here.
According to www.wtc.com, 4 WTC is located on the southeast corner of the 16-acre WTC site and will face directly onto the World Trade Center Memorial Park to the west. Scheduled for completion at the end of 2013, it will rise 977 ft from street level to 72 stories. The tower is intended to assume a quiet but dignified presence at the site while also serving to enliven the immediate urban environment as part of the redevelopment efforts of downtown Manhattan.
For more information about the World Trade Center’s rebuilding progress, including the latest construction images and video, visit http://www.panynj.gov/wtcprogress. A photo by Jennifer Hardyniec, a first-year structural engineering graduate student at Virginia Tech, shows another perspective of 4 WTC and received an Honorable Mention in the 2011 AISC Student Photo Contest.

Encouraging Young Women to Explore Engineering
Posted by Tasha Weiss on February 16, 2012 at 3:43 PM.
In the past decade, “Introduce a Girl to Engineering Day” has introduced more than one million girls and young women to the engineering field. Now in its 11th year, the national event will take place next Thursday, February 23, as part of Engineers Week. To find an event near you, click here.
The Introduce a Girl to Engineering Day program reaches out to girls in grades K-12 with positive messages about engineering careers and math and science education. Its mission is to provide girls and young women with mentors who can inspire their decision to become engineers and increase the number of women in the workforce. Currently only 20% of engineering undergraduates are women and only 10% of the engineering workforce consists of women.
Engineers Week enters its 61st anniversary next week, February 19-25, and was created by the National Society of Professional Engineers to raise public understanding of the importance of the engineering profession. The program reaches out to schools, businesses and community groups across the U.S. to provide various events and resources on becoming an engineer.
