George Washington Bridge Redecked with Prefabricated, Prepaved Steel Panels
The Port Authority of New York and New Jersey has embarked on a –37,000,000 project to totally replace the upper roadway of the 46-yr old George Washington Bridge. The scheme, chosen from...

Vibration Analysis of Plate-Grid Decks

James B. Eads and His St. Louis Bridge
Eads Bridge at St. Louis, a century old engineering achievement, was designed, promoted, and built by an intensely dedicated and self-educated man, James B. Eads. This structure was an...

Deck Slab Repaired by Fibrous Concrete Overlay
The concrete deck on the visitors' overlook facility at Libby Dam became badly cracked and in need of repair. It was decided to overlay the existing surface with 0.75-in. to 2-in. (18...

Structural Characteristics of Weathered Plywood
Plywood exposed for more than 21 yr to continuous weathering and use as the roof decking of portable hog houses was found to have strength properties comparable to those expected in new...

Design of I-Shaped Beams with Diaphragm Bracing
Cold-formed steel panels are used as wall sheathing, roof decking, or floor decking in steel framed buildings. Diaphragms formed by interconnecting these panels have considerable in-plane...

High-Temperature Drying of Thick Concrete Slabs
The foremost requirement for deep polymer impregnation of thick concrete slabs is thorough drying to remove all evaporable water from the pore system in concrete. To facilitate rapid repair...

Composite Steel-Deck Concrete Floor Systems
The use and application of composite steel-deck concrete floor systems in building construction both in the U.S.A. and Canada is presented. A comprehensive literature review on the topic...

Ultimate Load Test of Truss Bridge Floor System
An old pin-connected high-truss single-lane bridge, located in an area which will be flooded due to the construction of the Saylorville Dam, was tested to failure. Only the portion of...

Binary Flutter of Suspension Bridge Deck Sections
Wind tunnel experiments on models of suspension bridge deck sections with plate girders of various heights are made to show that binary flutter of suspension bridge deck sections can be...

Design Recommendations for Steel Deck Floor Slabs
The recommendations are based on the steel deck serving as the structural load-carrying element during the construction phase and the composite steel-deck concrete floor slab serving as...

Shear-Bond Analysis of Steel-Deck-Reinforced Slabs
A brief review of steel-deck-reinforced floor systems and resulting failure modes is presented, followed by the development and evaluation of design equations for one-way shear-bond capacity....

World's Third Longest Cantilever Bridge
This report includes the planning, design and construction procedure of the world's third longest double deck, cantilever bridge, Osaka Port Bridge, which was completed in...

Steel Stress-Ribbon Concept — Will It Save Money—
The stress ribbon structure, a fairly new and unusual concept, can be built with central sags of less than 2% of the span length using currently available materials and technology. Possibilities...

Stress Ribbon Bridge in Freiburg, Germany
A three span continuous stress ribbon bridge of 75, 130, and 138 ft, was built in downtown Freiburg, W. Germany, for pedestrian traffic. Structural analysis is similar to that of suspension...

Landmark Erie Canal Structure Rehabilitated
The lower level of the Broad Street Bridge, which dates to 1823, was an aqueduct which carried the Erie Barge Canal over the Genessee River in Rochester, New York. The history of this...

Enclosed Soak System for Deep Polymer Impregnation of Concrete Bridge Decks
Results of polymer impregnation of concrete slabs and a bridge deck to a depth of 4 in. are presented and examined. The criteria developed for drying the slabs and bridge decks to a depth...

Polymer-Impregnated Concrete: Field Studies
The principles developed in the laboratory for polymer impregnation of concrete to depths below the top layer of steel reinforcing rods were applied to the impregnation of large concrete...

Fifty-Year Development: Construction of Steel Hybrid Bridges
Hybrid construction of bridges has developed over the past 50 yr, beginning with composite concrete deck bridges during the twenties, progressing through prestressed and autostressed hybrid...

Short Span Bridges
Short span bridges, seemingly simple and innocuous structures, in fact embody many interesting problems and developments: The need to replace hundreds of thousands of bridges (safety and...
