Steel Shots: Knowledge and Discovery
Posted by Tasha Weiss on November 9, 2012 at 6:54 PM.
Pictured here is the Central Branch of the Seattle Public Library, located in the heart of downtown Seattle. Its unusual but compelling form demonstrates steel’s power as both an architectural and structural element. The library’s use of steel not only provides a strong structural framework, but also allows for great flexibility in interior programming and personal engagement with the library’s collections and spaces. The Seattle Central Library’s steel design parallels the mission of all libraries: Provide a solid framework for knowledge acquisition, but also allow individuals the flexibility to pursue discovery in a personal manner.

Fast-Track Railroad Bridge Replacements
Posted by Tasha Weiss on November 7, 2012 at 4:14 PM.
Two century-old railroad bridges located on East/West Stonington Harbor, Stonington, Conn., a critical link along Amtrak’s Northeast Corridor, were replaced late last year with new steel spans that were rolled into place over the course of a single weekend.
A new video by bridge engineering firm Modjeski and Masters, titled “The Fast Track: Rolling-In A Lasting Impression,” profiles the accelerated bridge construction techniques used to complete the bridge replacements, resulting in minimal disruption to Amtrak’s high-speed rail services and extra vertical clearance for watercraft vessels.
With more than 200 trains traveling the Northeast Corridor every week–nearly half of Amtrak’s nationwide ridership–it was critical to minimize any traffic disruptions. Furthermore, after discussions with local stakeholders, it was determined that the original bridge clearance was not great enough to facilitate the free flow of boats to and from nearby marinas. The railway consists of two ballasted tracks on the same alignment located on a causeway, with low clearance over harbor channels, approximately 800 ft apart.
Modjeski and Masters created the designs, which provided an additional two ft of clearance, and laid the groundwork for a quick transition. Working closely with Amtrak and Cianbro, the bridge contractor, the teams erected 1,200 tons of structural steel for the new bridge superstructures on roll-in falsework adjacent to the existing bridges.

LEED v4 Fifth Public Comment Period Ends Dec 10
Posted by Tasha Weiss on November 5, 2012 at 5:52 PM.
The U.S. Green Building Council (USGBC) recently opened the fifth public comment period for the proposed update to its LEED green building program, LEED v4. The comment period, which will close on December 10, enables the building community to view the most recent draft of the LEED rating systems and provide comments on any substantive changes.
“LEED v4 will have the greatest impact of any rating system we’ve developed by focusing on building performance and rewarding innovative product manufacturers who offer best-in-class products,” said Scot Horst, senior vice president, LEED, with the USGBC. “LEED v4 will help change the way project teams think, integrate, plan, execute and operate their buildings.”
When fully launched in 2013, USGBC intends for LEED v4 to provide an improved user experience with a more intuitive and efficient certification review and documentation process. The simplified reporting requirements will be thoroughly refined and tested by the LEED v4 beta testing group, the first crop of projects to pursue LEED v4 certification. The beta process enables project teams to engage with a pre-ballot version of LEED v4 with guided support from USGBC.
USGBC’s Greenbuild International Conference and Expo, taking place November 14-16 at the Moscone Center in San Francisco, will give users an additional opportunity to explore LEED v4, including the new technical content and credit language. Public forums and educational sessions will be held to help stakeholders better understand the next draft, and the event will also serve as a platform to debut new resources designed to enhance the LEED user experience. AISC, along with the Steel Recycling Institute, is a Silver Sponsor of the conference and will be exhibiting at booth 3878N.
LEED v4 drafts and the public comment tool are now available on the newly re-launched USGBC.org website, at https://new.usgbc.org/leed/v4. LEED v4 is expected to be balloted in June 2013.
Steel Shots: A (Reading) Room with a View

They always tell you to keep quiet in the library.
But the reading room of San Diego’s new downtown children’s library, called the San Diego Library Dome, might elicit a number of “oohs and ahs.”
That’s because it’s housed in a 140-ft-tall steel-and-glass dome, on top of a nine-story building, with magnificent views of downtown San Diego, the harbor and the Coronado Bridge.
The children’s library is part of an expansion project that will add 498,000 sq. ft of space to the city’s Central Library, effectively doubling the size of the current library. The new $185-million building will also feature a technology center, outdoor plaza and cafe, 350-seat auditorium, 400-seat multi-purpose room, teen center and two levels of underground parking. In addition, two floors of the library, totaling 76,000 sq. ft, will be used for a charter school serving up to 400 students. The building is also being designed and constructed to achieve LEED Silver certification.
The dome not only provides a beautiful reading environment but also a new architectural icon for the city. Comprised of steel sails with thousands of steel connection points to support the aluminum panel covering, which is perforated with thousands of light points, the dome’s design allows natural light to illuminate the space below.
The dome required 285 tons of hollow structural sections (HSS) in all, and the largest steel sail measures 123 ft high and 53 ft wide. Each sail is comprised of multiple curved members, which are 6 5/8 in. in diameter and 1/2 in. thick. The largest sail has 59 curved members, 5 trusses, 20 spreaders, 102 stainless steel bars, 204 rod ends, 40 cables, 40 swage turn buckles, 40 swage ends and 20 spreader packs. Curved members lace the cross sections to form the eight 13-ton steel sails, which were individually hoisted into place.
Roughly 60% of the sails were assembled in Utah prior to shipping, and the remaining sails were assembled on site. SME Steel Contractors, Inc., West Jordan, Utah (an AISC member/AISC Certified Fabricator) was the steel fabricator and erector for the project. The dome topped out on July 3 and was completed on August 31. The new library is scheduled to open this coming summer.
