Steel in the News
Advance Steel 2015 Now Available
Posted by Tasha Weiss on April 15, 2014 at 4:52 PM
Autodesk has released its new Advance Steel 2015 software for steel detailing.
This latest version of Advance Steel provides structural steel detailers, fabricators, engineers and contractors with 3D modeling tools, built on the familiar AutoCAD platform, to help accelerate more accurate detailing of structural elements, steel connections and plates. It is also designed to reduce time to fabrication by automatically generating shop and general arrangement drawings, creating bills of materials and producing CNC files directly from designs.
With interoperability between Autodesk Revit, Autodesk Navisworks and other BIM software, Advance Steel also provides a way to connect BIM-based design and construction through fabrication.
Advance Steel 2015 was unveiled at last month’s NASCC: The Steel Conference in Toronto and is the first branded product to come out of Autodesk’s acquisition of key technologies from Graitec.

Biggest-Ever Bridge Slide
Posted by Tasha Weiss on April 14, 2014 at 5:35 PM
The largest bridge slide ever was completed last week at site of the Milton-Madison Bridge over the Ohio River between Milton, Ky., and Madison, Ind., when the new bridge made its 55-ft journey from temporary piers to permanent, refurbished piers. Spanning nearly a half mile, the truss of the Milton-Madison Bridge is now the longest bridge in North America to be slid laterally into place.

The slide began on Wednesday morning but was halted in the late afternoon due to high winds over the Ohio River. Walsh Construction, who is building the bridge, brought in materials from the Louisville-Southern Indiana Ohio River Bridges Project to help deal with windy conditions and assist in synchronizing the slide onto the five permanent piers, which allowed the slide to resume on Thursday morning at about 8 a.m.
“It’s great to see the bridge completed and sitting in its permanent location,” said Dav Kessinger, project manager for the Kentucky Transportation Cabinet. “This bridge will serve the area well for decades to come.”
“This is truly a historic accomplishment for everyone involved,” added Kevin Hetrick, project manager for the Indiana Department of Transportation (INDOT). “The people of Indiana and Kentucky should be proud to be a part of this amazing engineering feat.”
Polished steel sliding plates were secured on top of the refurbished piers. Steel cables and eight computer-controlled hydraulic jacks were used to pull the bridge through a series of grabs and pulls until the bridge was slid into place. The 30-million-lb new steel truss bridge is 2,428-ft long and 40-ft wide with two 12-ft lanes and 8-ft shoulders – twice as wide as the old bridge, which opened in 1929. A 5-ft-wide cantilevered sidewalk will be added to the structure in the coming months.
Now that the slide is complete, it will take approximately a week to complete inspections, road connections to the bridge and other work before the bridge is reopened to traffic.
The Milton-Madison Bridge Project – a joint effort between the Indiana Department of Transportation and the Kentucky Transportation Cabinet – has received several state and national engineering awards for innovation.

The article “Move That Bridge” in the February 2012 issue of MSC also describes the project in detail and explains how the decision to use the innovative sliding technique stemmed from the system’s success on the Capilano River Bridge project in Vancouver, Canada.
Steel Shots: Innovation at its Finest

The Newport Beach Civic Center and Park in Newport Beach, Calif., is a National award winner in AISC’s 2014 IDEAS2 awards program.

Every year, AISC’s IDEAS2 Awards recognize the most innovative new steel structures in the U.S. and the importance of teamwork, coordination and collaboration in fostering successful construction projects.
This year’s 12 IDEAS2 winners were announced at the 2014 NASCC: The Steel Conference last month in Toronto. Covering an array of project types, they demonstrate the flexible and effective solutions provided by structural steel on a wide variety of building projects.
A panel of design and construction industry professionals identified National and Merit winners in three categories, based on constructed value: less than $15 million, $15 million to $75 million and greater than $75 million. In addition, the panel awarded a Presidential Award of Excellence in Engineering to one project for outstanding structural engineering achievement.
You can view this year’s winners in AISC’s press release, and all of them will be featured in the May issue of Modern Steel, with detailed project descriptions and photographs of each.

Engineering Journal Q2 Now Online
Posted by Tasha Weiss on April 10, 2014 at 5:38 PM
The second quarter 2014 issue of Engineering Journal is now available online. Click here to view, print and share the current digital edition.
This issue of Engineering Journal is the first of two issues with a special focus on the "simple for dead load--continuous for live load" -- or SDCL -- design concept. The premise behind the concept is that girders erected as simple spans can be made to function under live load as continuous spans by providing continuity with a unique field connection. In addition to covering research, the journal will highlight two successful SDCL bridge projects from the engineer's perspective.
Article searches for the complete collection of EJ remain available at www.aisc.org/ej. Downloads of current and past articles in PDF format are free to AISC members and ePubs subscribers. Non-AISC members may subscribe to EJ at the AISC bookstore.
2014 Excellence in Hot-Dip Galvanizing Awards Winners Announced
Posted by Tasha Weiss on April 9, 2014 at 5:24 PM
The American Galvanizers Association (AGA) recently announced the winners of this year’s Excellence in Hot-Dip Galvanizing Awards. More than 100 projects representing the versatility of hot-dip galvanizing were submitted and judged online by a panel of architects and engineers.
This year’s highest honor, the Most Distinguished award, was given to the San Diego Central Library. It features a hot-dip galvanized steel facade, including the magnificent three-story arched domed terrace. (The dome portion of the project is also a National Award winner in this year’s AISC IDEAS2 Awards program and will be featured in the May issue of Modern Steel.) In addition, more than $75 million, or 40% of the project cost, was donated by more than 3,000 private individuals – a record for funding a public works project of this kind.
The Lifetime Achievement award, which recognizes a galvanized project with at least 15 years of service, was given to the Bridges of Stark County in Ohio. In the early 1970s, Stark County engineer Rich Larocco decided to dismantle the bridges, galvanize the steel beams, and reinstall them in an effort to lower maintenance costs. After seeing the impact of the recycled bridges, Stark County continued to install new galvanized bridges.
In addition to these two awards, 13 other projects were selected to represent the best of the best in 12 categories that are common sectors for the use of hot-dip galvanized steel. In addition to the Bridges of Stark County, three other categories, Bridge & Highway, Civic Contribution and Duplex Systems recognized bridge and/or bridge-related projects. Another popular theme in this year’s winners were projects affiliated with universities, including a classroom building and parking garage.
