Software for Optimum Design of Highway Bridge Beams
A software system for analysis and optimum design of welded plate beams subjected to AASHTO highway bridge loads and specifications is described. The system has the capability to design...
Interactive Bridge Optimization Program
This paper presents the development of a design methodology that includes the structural optimization process as an integrated component of girder bridge design. The optimization process...
Finite Element Analysis of Structural Details in Large Steel Bridge Superstructures
Various approaches for the finite element modeling of the connection details in large steel bridge superstructures are presented. It is noted that an accurate analysis of these details...
Computer Simulation of the Overload Behavior of Steel Multigirder Bridges with Cracked Girders
Various approaches of determining the structural response of steel multigirder bridges with cracked girders are presented. It is noted that linear finite element packages with three dimensional...
Advances in Analysis of Structural Masonry
The papers in this book were presented at the technical session, Advances in Analysis of Structural Masonry, at the ASCE Structures Congress '86 held in New Orleans, LA, on...
Sunshine Skyway Nears Completion
The new Sunshine Skyway Bridge over Tampa Bay in Florida replaces an older structure that had been severely damaged when a ship rammed it during a 1980 storm, taking 35 lives. Its central...
Bridging the Joints in Bridges
Most bridges are designed with gaps in them. The cracks allow bridges to expand and contract as the temperature changes. But water can enter these gaps and foul bearings and structural...
Steel Bridge Counterattack
In bridges, for years steel has been losing market share to concrete, but now the steel industry is making an impressive comeback. One reason is use of load-factor design, which has cut...
Filling the Cracks
Engineers, highway officials, and manufacturers are working together to develop new products to rehabilitate cracked bridge decks. Polymer concrete overlays are among the many remedies...
Shopping for a New Bridge Coat
Total shop coating of new steel bridges appears to be the best armor against corrosion. This alternative is one of three techniques for diminishing the difficulty and expense of painting...
Celebrating a Conquest
During construction of the San Francisco-Oakland Bay Bridge, which marked its 50th anniversary on Nov. 11, 1986, great public attention was paid to the high-climbing steelworkers, but...
Designing for Flow
Geotextiles used for in-plane drainage can carry surprisingly large amounts of water within their structures. These composite drains, known as sheet drains, prefabricated drainage composites...
Jet Grouting: Snail's Pace of Adoption
Jet grouting is grouting of soil, but the process, the equipment and the subsurface product are different from the familiar ones. Here the cement grouting is mixed in situ with the surrounding...
Application and Performance of Structural Materials and Exterior Facades
The papers in this book present some of the current thinking associated with today's construction materials as well as the results of research which is directed toward the...
Experimental Assessment of Performance of Bridges
Among the papers in this book, five assessed the global bridge behavior and the three concentrated on bridge decks. The bridges assessed include prestressed steel plate girder and truss...
Use of Private Contracting in Highway Maintenance
Managing the business of highway and bridge maintenance in this country is largely a function of the public sector. As in the private sector, economic realities during the past decade...
The United States Used to be a Great Country...
Up until 20 years ago, the American highway departments did a good job of maintaining bridges and they kept streets well paved. The public works departments maintained the water and sewer...
Golden Gate Bridge: Deck Replacement
A major inspection of the Golden Gate Bridge in 1968-69 found the reinforced concrete roadway of the Bridge to have widespread defects and local failures. Further investigations found...
Tunnel and Bridge Construction with Minimum Disturbance to Overhead Services
The rapid growth of pipe jacking over the last 20 years and the improvement and development of methods in terms of lengths of drive, size and ability to work in varying ground conditions...
Financing the Golden Gate Bridge?Past and Present
This paper discusses the financial side of the project, which was a very innovative solution that provided federal revenue not only for the Bridge Redecking Project, but more importantly...
