  • About the Edition

    Of the approximately 25,000 bridges in Iowa, 28% are classified as structurally deficient, functionally obsolete, or both. The state of Iowa thus follows the national trend of an aging infrastructure in dire need of repair or replacement with a relatively limited funding base. Therefore, there is a need to develop new materials with properties that may lead to longer life spans and reduced life-cycle costs. In addition, new methods for determining the condition of structures are needed to monitor the structures effectively and identify when the useful life of the structure has expired or other maintenance is needed. High-performance steel (HPS) has emerged as a material with enhanced weldability, weathering capabilities, and fracture toughness compared to conventional structural steels. In 2004, the Iowa Department of Transportation opened Iowa"s first HPS girder bridge, the East 12th Street Bridge over I-235 in Des Moines, IA. The objective of this project was to evaluate HPS as a viable option for use in Iowa bridges with a continuous structural health monitoring (SHM) system. The scope of the project included documenting the construction of the East 12th Street Bridge and concurrently developing a remote, continuous SHM system using fiber-optic sensing technology to evaluate the structural performance of the bridge. The SHM system included bridge evaluation parameters, similar to design parameters used by bridge engineers, for evaluating the structure. Through the successful completion of this project, a baseline of bridge performance was established that can be used for continued long-term monitoring of the structure. In general, the structural performance of the HPS bridge exceeded the design parameters and is performing well. Although some problems were encountered with the SHM system, the system functions well and recommendations for improving the system have been made.

Generally, a high-strength struc-tural steel is viewed as necessarily superior to mild steel. A new skewed two span continuous steel girder bridge was constructed and opened to traffic recently.

High-performance steel (HPS) also provides increased strength, as well as greater ease in welding. HPS has only half the carbon and one-tenth the sulfur content of conventional steel. The low-carbon content means that little or no preheating is needed to weld components together, which reduces both construction time and costs.

This new document has been expanded to include prefabricated/modular steel bridges using steel rolled beams and hollow structural sections and also corrugated steel pipe and corrugated steel plate as viable materials for bridge construction.

Structural Act ion of Steel Girder Structures. Box girder, rolled girder and plate girder bridges are primarily flexural structures which carry their loads by bending between the supports. The degree of continuity of the steel girders over their intermediate supports determines the structural action within the steel bridge.

The main. successful that the launching method was utilized to construct a nearly identical bridge a few years later. The first steel bridge to be launched in the United States is believed to be a Kansas City Southern Railroad box girder bridge near Redland, OK in (Durkee ).

A bridge falling under this category is suspended from cables. The suspension cables are anchored at each end of the bridge (span a distance of approximately to feet).

built in Performance has been excellent. The ft. and ft. continuous lengths of deck slab on these bridges are believed to be the longest built to date supported on precast, prestressed girders. The Los Penasquitos Bridge in California was a PCI award winner.

A primary reason for using conti-nuity with precast, prestressed. Bridge construction typically involves methods using relatively discrete elements, like piles and girders, which are assembled piece by piece.

Over the past 50 years, however, construction methods have evolved to reduce traffic impact, facilitate building in congested areas, reduce overall construction schedules, and improve the long-term.

The length of the five spans of the bridge is arranged as 85,and 85 m, and the full length of the bridge is m. The section of the main beam is a high-performance concrete bridge decking combined with a separated open steel box girder.

evaluation of bridge members. Results from an example site indicate high safety levels despite the large numbers of permit vehicles allowed. More thanbridges in the United States are reported to be structurally deficient (!l. Many of these bridges, however, were designed and constructed.

It’s easier to inspect and determine the structural state of a steel bridge where all the components are visible. The long-term durability and cost-effectiveness of steel bridges will be further enhanced by the use of high performance steels with weathering capabilities. At one time or another, much has also been made of problems with fatigue in.

With the National Interstate Highway System construction boom in the late 's and early 's, the use of continuous jointless bridge construction began a real growth spurt. By the mid's, Tennessee and five other states had adopted continuous bridges with integral abutments as standard construction.

Reasons for Jointless. In a study by the US Federal Highway Association, high-strength steel was found to provide lifetime cost savings of up to 18 % and weigh 28 % less than traditional steel bridge design materials. Designers and engineers can now specify new high performance steels that have yield strengths of N/sq mm and N/sq mm.The structural advantages of using steel include its lighter weight, which means lighter foundations and lower erection costs.

Steel is ideal for short-span bridges because of its durability, ease of maintenance and ease of construction. Today's bridge engineers face unlimited demands on limited resources.
