A Fatigue Reliability Model for Railway Bridges
A fatigue reliability model is described for safety evaluation of steel railway bridges. The model is a function of six independent random variables and can accommodate different types...
Probabilistic Evaluation of Bearing Capacity of Shallow Foundations
A probabilistic model is developed to evaluate the bearing capacity of shallow foundations. The bearing capacity formulation proposed by Terzaghi is used but with the bearing capacity...
Fatigue Strength of Welded Joints Under Broadband Loadings
Twelve welded high strength steel cruciform specimens were tested under stochastic loadings to determine the influence on fatigue life of the bandwidth of the loading process. Constant...
Low-Cycle Fatigue Prediction for Ramberg-Osgood Type Materials
The prediction of low-cycle fatigue crack growth is successfully made by an equation employing the J-integral range. This equation, originally proposed by Dowling and Begley, is analogous...
A New Probabilistic Model for the Fracture Toughness of Concrete
Scatter of strength and toughness parameters as well as scale effect are often observed in brittle materials such as concrete. The recently developed Crack Diffusion Model is utilized....
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...
Metrication of Construction?A Message to the American Society of Civil Engineers
The author discusses the reasons for metrication of the U.S. construction industry, describes the Canadian experience in this area, and outlines the necessary steps to alleviate the metrication...
Design of Latticed Steel Transmission Structures
This standard,
Taming Tornado Alley
Some structures�such as nuclear power plants�need complete protection from tornadoes regardless of the high costs of design and construction. Public facilities need protection too, but...
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...
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...
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...
Use of the Break-Off Method for the Evaluation of High Performance Concrete
The Break-Off test is one of the recent developments for testing in-place concrete strength. This research was undertaken to investigate the reliability of the Break-Off test as a measure...
Application of SMA Technology in Georgia
In 1991, the Georgia Department of Transportation participated in a cooperative effort with the Federal Highway Administration to conduct one of a series of field evaluations of Stone...
A Laboratory Investigation on Long-Term Performance of Asphalt Concrete Treated with Antistripping Additives
Asphalt concrete pavement is susceptible to moisture damage and the damage caused by repeated freeze-thaw cycles is a major problem. This paper summarizes a laboratory investigation for...
