The Parking Problem
Corrosion of parking garage decks has become a multi-billion dollar problem, caused primarily by deicing salts that seep into the concrete and attack reinforcing steel. Design and construction...

U.S. Navy's First Double Deck Pier
The present single level concept of pier construction limits the pier-side service to the fleet. With the ever increasing requirements for utilities to the ships, and maintenance and training...

Tacoma Terminals Pier Designed for Economy
This pier is a representative and highly refined sample of what is known as the Puget Sound system of construction, an economical system that maintains the durability necessary in the...

Cable Stays Catch On
The three completed cable stayed bridges in the U.S.�Pasco-Kennewick in Washington, Luling-Destrehan in Louisiana and East Huntington in West Virginia�will soon be joined by another half...

Rehabbing under Traffic
Redecking the Golden Gate Bridge with a light weight orthotropic steel plate deck left the 49 year old monument 11,000 tons lighter, 2 feet wider, and ready to carry traffic for the next...

Timber in Bridges of West Coast
Experience has shown that timber can function very well as a bridge material. Proper inspection procedures combined with a structured maintenance program can improve the performance of...

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...

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...

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...

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...

Proposed Design Criteria for Composite Steel Deck Slabs
Composite steel deck slabs have continued to gain popularity; today they are one of the predominant means of floor slab construction in most typical buildings. The term 'composite...

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...

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...

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...

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...

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....

Specifications for the Design and Construction of Composite Slabs and Commentary on Specifications for the Design and Construction of Composite Slabs
Composite slab construction is defined as a system comprising normal weight or lightweight structural concrete placed permanently over cold-formed steel decking in which the steel deck...

Jointless Bridge Decks
Deck joints in a bridge are the source of many problems over its lifetime. In time, chances are good the joint will leak, permitting water and salt to leak through. Often this leads to...

Redecking with Precast Keeps Traffic Moving
The Woodrow Wilson Memorial Bridge in Washington, D.C. could not be closed to traffic while a new deck was constructed. The engineers designed a precast prestressed and post-tensioned...
