Steel Beats Concrete for Idaho Bridge
As an alternative to prestressed concrete design, the State of Idaho and the Federal Highway Administration encouraged the use of cable-stressed steel girder design for the Bonners Ferry...
Georgia's Low-Cost Approach to Rehabilitating Concrete Pavements
A six step approach to rehabilitating concrete pavements is described. The six steps are: (1) Slab stabilization; (2) slab replacement, where necessary; (3) repair of spalls; (4) resawing...
Sewers: Repairing Beats Replacing
Rehabilitating decaying sewers can be up to 70% less costly than replacing them. Yet most sewerage agencies wait until a pipe collapses before taking action, necessitating expensive emergency...
Frontiers in Hydraulic Engineering
These proceedings include approximately 140 papers presented in the ASCE Hydraulics Division Specialty Conference, August 1983, Cambridge, Mass. The principal aim of the conference was...
Characterization of Offshore and Coastal Ice Conditions
Seasonal sea ice conditions typical of nearshore coastal zones are reviewed. Prominent ice features influencing design ice conditions for offshore structures are described. This paper...
Design of Prefabricated Offshore Structures for Ice Forces
The design of fixed offshore structures to resist forces from sea ice features is reviewed. The emphasis is on prefabricated structures constructed elsewhere, towed to location and installed,...
Design of Manmade Offshore Islands for Ice Forces
Approximately sixty percent of the undiscovered oil and fifty percent of the undiscovered gas probably lies in the sedimentary basins offshore Alaska (USGS 1980). Because of this hydrocarbon...
Design of Port and Coastal Structures for Ice Forces
Design of ice-affected port and coastal structures cannot be addressed in a few single specific terms, but must instead account for a matrix of elements differing at each site. Evaluation...
Design of Offshore Pipelines for Ice Environments
Design and installation of offshore pipelines in cold regions requires special care. Low ambient temperatures may cause increased friction losses in oil and gas lines due to wax crystallization...
Design of Bridges for Ice Forces
Sources of knowledge on ice forces and ice effects on bridges are listed and discussed briefly. Comments are made on experience of damage by ice and on the influence on bridge costs of...
Design of Navigational Structures for Ice Forces
An overview of ice conditions and the types of ice action that are hazardous to navigational structures is presented. Depending on the circumstances, ice failure against structures occurs...
Design of Submerged and Floating Structures
The objective of this paper is to present an overview of the state-of-the-art of ice engineering as applied to submerged and floating structures. Five specific design studies are reviewed,...
In Search of Ancient Engineers
Many examples of pre-Columbian civil works have been uncovered in North and South America. Some reflect well-organized technologies comparable to those of the Old World of the same time...
Structural Steel Details: Is Responsibility a Problem?
Because structural engineers are leaving design of structural steel connections to fabricators, the problem of responsibility for those details has arisen. This article explores a variety...
Record Concrete Box Girder Spans Houston Ship Channel
The Houston Ship Channel Bridge is an American advancement of the cast in place, post-tensioned, segmentally constructed, concrete box girder design. In spite of the complex and unique...
Pile Construction Practices in Arctic Regions: State-of-the-Art
Pile installation techniques in cold regions include drill and slurry, and driven methods for foundation designs. In the past, piles used for structural support in permafrost have consisted...
Cold Regions Concreting
The quest for energy and other riches of the earth in the north regions, the establishment of permanent scientific and defense stations in cold regions, the high cost of project and construction...
Flanged Reinforced Concrete Flexural Members
Design aids in the forms of charts and tables are available for design of reinforced concrete flexural members. Many of these design aids were developed for design of rectangular cross...
The Civil Engineer and the Decay of America's Infrastructure
With the infrastructure of the United States continuing to deteriorate, the problem becomes who will decide how much to spend in both repairing, maintaining and building new facilities...
Passive Solar and Daylighting Cut Building's Energy Use
The headquarters building for Gulf Mineral Resources Co. near Denver requires about one-quarter of the energy generally used in a new conventional building. A double skin provides a thermal...
