A Systems Reliability Approach to the Safety of Steel Connections
A methodology is presented to determine the probability of failure of steel connections using a systems approach. Results indicate that connection safety evaluations which do not use this...
Bridge Overloading Criteria
Considerable concern is being expressed by the public and government agencies over the deteriorating state of the country's infrastructure. At the same time, there is a general feedling...
A Multiple Presence Load Model for Bridges
This paper utilises weigh-in-motion data to simulate multi-lane traffic crossing short span multiple-lane bridges. In this manner the reduction factors for a multiple lane bridge are derived....
On the Fatigue Loading for Local Components
Fatigue provisions in the North American Codes for design of highway bridges may not be applicable to the design of local components which are subjected to high axle overloads and dynamic...
Live Load Models Based on WIM Data
The objective of the paper is to present the results of weigh-in-motion (WIM) measurements carried out in Michigan. Selected bridges were instrumented and truck weights and axle configurations...

Seismic Rehabilitation of Seattle's Pier 69
The Port of Seattle, one of the largest on the west coast of North America, made a strong statement regarding their support for reusing existing structures when a decision was made to...
Pre-Compression of Concrete Breasting Dolphins Solves Construction Problem
A roll-on/roll-off ferry terminal was built in Quincy, Massachusetts in 1989 as part of a marine transportation system to support construction of the sewage treatment facilities proposed...
West Point Temporary Construction Dock
The West Point temporary construction dock is designed to provide construction access for the West Point treatment plant project located in Seattle, Washington. The dock plays a major...
Replacement of a Deteriorated Steel Sheet Pile Bulkhead
This paper presents a life history of a marine steel sheet pile bulkhead, over 35 years old, that has been exposed to a salt water environment with minimal maintenance or repair in the...
Two-Dimensional Hydraulic Analysis of the Owensboro Bridge and Approaches
The Kentucky Transportation Cabinet, Department of Highways, is working with the Indiana Department of Transportation and the Federal Highway Administration to plan, design, and construct...
Probability of Bridge Failure Due to Pier Scour
Methods have been presented for computing the probability of bridge failure due to pier scour either using a maximum scour depth model or a time-dependent model. The probability of failure...
Seattle Swings Again
The 1992 Outstanding Civil Engineering Achievement Award went to a bridge that the experts said couldn't be built�a concrete segmental box girder swing bridge with twin leaves...
The OCEA Awards of Merit
Submerged rock weirs help tame the Mississippi River, high head pump storage provides power to a community safely and inexpensively, and the world's largest cantilevered hangar...
OCEA, American-Style
A truly All-American contingent, the nominees for this year's Outstanding Civil Engineering Achievement award span the continental U.S., Alaska and Hawaii. The scope of the...
Building Better Bridges: Concrete Vs. Steel
The authors debate the merits of concrete segmental and steel bridge design and construction based on five criteria: initial and life-cycle costs; structural advantages; durability; construction...
The Role of Nondestructive Testing in Assessing the Infrastructure Crisis
At present the role of nondestructive testing in the evaluation of infrastructure deterioration is an extremely limited one. In the Author's experience this is, in part, due to a reluctance...
Principles of Infrared Thermography and Application for Assessment of the Deterioration of the Bridge Deck at the Zoo Interchange
This paper details the principles of infrared thermography from the underlying theoretical considerations to the physical constraints involved with performing the test. Infrared (IR) thermography...
Realistic Specifications for Steel Bridge Painting
Specifications play a vital role in a steel bridge painting contract. They not only can ease problems with painting construction, but can also provide a common standard for all parties...
