Structural fire engineering is heating up in the U.S. and Europe, thanks in large part to the "traveling fires" observed on Sept. 11, 2001, at the World Trade Center.
Mike Current says he almost had a nervous breakdown in anticipation of the first lift of the site-preassembled, glass-enclosed pedestrian bridges that link CityCenterDC's 11-story office buildings across a 24-ft-wide alley.
The conventional reinforced-concrete frames of the six 11-story buildings that stand in place of the razed Washington, D.C., convention center don't hold a candle to the innovative space truss that supported the old exhibit hall's clear-span roof.

Designers attending the 2013 AIA National Convention and Design Exposition in Denver, on June 20 to 22, acknowledged that the AIA documents and the new guide released with them represent progress. But they still expressed concerns about sharing BIMs with contractors.“We all know this is the future, and [developing standard

Bloomberg (R) and City Council Speaker Christine C. Quinn (D).The task force's 33 proposals for commercial and

To improve construction practice, it will now focus on larger research concepts that could have an impact on all structures, not just buildings.The group has picked high-strength reinforcing steel for its first wide-impact research program. The goal is to update the concrete code, which currently limits the use of higher-strength rebar in all types of structures.Pankow
Related Links: Timber Tower Research Project Softwood Lumber Board Arup San Francisco The U.S. is lagging Europe, Canada and Australia in the massive-timber tall-building movement—heating up because renewable, low-carbon-footprint timber is the most sustainable structural material. A feasibility study released last week for a 42-story concrete-jointed mass-timber frame—considered supertall in a world in which the tallest timber building is only 105 ft—could begin to change all that by stirring up interest in tall timber structures in the U.S. and even providing grist for the mill for supertall timber towers elsewhere.Under the Timber Tower Research Project, a team from the Chicago
Now that proposed Superstorm Sandy-triggered changes to New York City zoning are out for public review, building owners, designers and contractors are eagerly awaiting the second piece of the post-Sandy regulation puzzle: proposed modifications to the city's building code. The adjustments to the two sets of regulations should go a long way toward aiding the design and construction of buildings that are safer and more resilient when exposed to floods and other major climate-related events, says Robert D. LiMandri, New York City's commissioner of buildings. Drawing Courtesy of the New York City Dept. of City Planning Possible Modification: Proposed rules
When the project team started plotting its construction strategy for The Shard, no one in the U.K. had ever planned a 306-meter-tall building or worked at such lofty heights.
