Bridges
The Federal Highway Administration estimates that nearly one-third of
America’s 594,000 bridges are either structurally deficient or
functionally obsolete. Steel bridges offer viable design
solutions for bridge owners
because they are durable, cost-effective, and offer ease of maintenance
and construction. For more advantages to steel bridges, click

High-Performance Steel: Research to Practice: by
William Wright
A new grade of high-performance structural steel, HPS-485W, is now
commercially available for highway bridge construction. This is the
first product developed under a highly successful cooperative research
program between the Federal Highway Administration (FHWA), the U.S.
Navy, and the American Iron and Steel Institute.
Emerging Construction Technologies: High
Performance Steel
High strength steels have been available for years, but their use
required more welding control and fabrication processes than
conventional strength steels. For this reason few bridge owners have
been willing to risk potential problems in fabrication, eventhough the
design could be more efficient with higher strength steel.
Team Honored for Developing High Performance
Steel For Bridges By Mary Zoccola
A team consisting of members from the Carderock Division, the American
Iron and Steel Institute (AISI) and the Federal Highway Administration
(FHWA) received the 1997 Civil Engineering Research Foundation (CERF)
Charles Pankow Award for Innovation.
Focus on High-Performance
While there have been many advances in steel-making technology over the
last 20 yrs., today structural steels in the United States are not very
different from those used 20 years ago.

HPS Success
Integrating high-performance 70 ksi steel (HPS) with traditional 50 ksi
steel yielded a design that cost 10% less than the lowest concrete
bid.
