Composite Steel Deck Bridge: An Experimental Study
Composite steel decks with steel fiber reinforced concrete (SFRC) were developed, aiming to improve the durability of the deck pavement and to increase the rigidity of the deck plate in...
Dynamic-Fatigue Response of Continuous Composite Bridges
The dynamic response of continuous composite bridges and the influence of fatigue loading at resonance frequency on the structural response are investigated. It is shown that cracking...
Application of Preflexed Composite Beams to Continuous Bridges
A preflexed beam is a type of concrete encased steel beam of which prestressing has been introduced in the lower flange concrete. Recently, the preflexed composite beams were applied to...
Recent Research on Composite Structures for Building and Bridge Applications
Continuing research has been carried out at Lehigh University on composite structural members, joints, and overall systems. This paper summarizes the results of research on four selected...
Seminar Summary and Research Needs
All the papers presented in the technical sessions of the seminar are summarized and, in some cases, commented upon. The needed research in composite and mixed construction is described....
Timber Bridge Decks
The portion of the nation's 500,000 bridge decks that are made of timber has been declining for years, as the old timber ones on secondary road bridges are rebuilt, in most...
High Strength Steel
A
A Road to Recovery
Inspections of the Golden Gate Bridge revealed that the bridge had localized corrosion near its expansion joints, corrosion of its reinforcing steel, and was severely contaminated with...
Risk Analysis for Ship-Bridge Collisions
The authors have developed a propriety software package which has been successfully used to perform risk analyses for several high-level bridge structures across major waterways in coastal...
Coping with Litigation
Engineers should learn legal philosophy, even though it seems unrelated to traditional technical practice. Monitoring changes in legal theory that may increase engineers'...
Floating Bridge for 100 Year Storm
In 1979 the west half of the Hood Canal Floating Bridge, built in 1960, in Seattle broke up and sank during a storm that lasted eight hours with winds of 80 mph and gusts over 100 mph....
Record Bridge Replacement
Jacks Run Bridge had to be rebuilt in one year instead of the usual two to three. So the Pennsylvania Department of Transportation spearheaded the quickest replacement of a major bridge...
Bridging Twin Ports
The Major Richard I. Bong Memorial Bridge, part of U. S. Highway 2, connects harbors at Duluth, Minn. and Superior, Wisc. The new highway link was designed to relieve congestion on nearby...
Who Should Design Bridges?
For many years Design-Build-Proposals have been common practice in Europe (except in the UK). Structures in these countries are 20% more economical than similar projects in the U. S.,...
The Impact of the I-664 Bridge-Tunnel Crossing on Sedimentation
A sedimentation evaluation was made of the proposed I-664 Bridge-Tunnel complex across the James River, Virginia. This paper briefly describes the procedures used and the results obtained...
Investigation of Design Criteria for APM Guideways
Designers have relied mostly on the provisions of the American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications for Highway Bridges. Sometimes...
Nine Years' Service with Deep Polymer Impregnation
A test installation of deep polymer impregnation was applied to a heavily traveled bridge deck in Bethlehem, Pennsylvania, in 1975. The deep polymer impregnation process involved drying...
Analysis of Cracking of I79 Bridge at Neville Island
A large crack was discovered to form in a girder of the I-79 Glenfield Bridge over the back channel of the Ohio River near Pittsburgh on January 28, 1977. A section of the girder containing...
Clearing the Decks
Cathodic protection, an electrical-chemical process that prevents corrosion of steel rebars on bridge decks, is rapidly gaining acceptance by highway engineers and state highway departments....
New Cables for Old
In an eingineering first, the main suspension cables will be replaced on New York City's Williamsburg Bridge without closing it to traffic at any time. According to the design...
