Subway
Peachtree Center Station is the only mined transit station in the U.S. using reinforced native rock for permanent support. The station, serving some 34,000 patrons a day, is the largest...
Hydro Recovery
The largest water utility in southern California is discovering that it makes sense to generate electricity too. During the past four years, the Metropolitan Water District of Southern...
Bridge
Seven Mile Bridge is the longest, continuous precast post-tensioned segmental concrete bridge in the world. In addition to its function as a main artery connecting the Florida mainland...
Building Trends: The View from Houston
Highligts of the major changes in building design and construction over the past decade are presented from a structural engineer's viewpoint. The areas covered include: (1)...
Forensic Engineering: What Role for ASCE?
Responding to heightened concern within and without the American Society for Civil Engineers (ASCE) about failures of engineered structures and other works, ASCE formed two commitees to...
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...
Pavement Management Systems: Selecting Maintenance Priorities
Realization of the need to maintain a safe, serviceable network of highways in the US has led to the development of a systematic, consistent procedure for managing resources necessary...
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...
A Market Pricing Approach to Fares
The Chicago Transit Authority's (CTA's) historical 'one city - one fare' policy overlooks an important principle elucidated in the current...
Managing Limited Transportation Resources in Pennsylvania's Department of Transportation
This paper will not describe systems, but rather a management approach which has proved successful in the Pennsylvania Department of Transportation. The following examples illustrate the...
Managing for the Eighties
In a period where fiscal constraints will mandate a new approach to managing limited financial resources, serious consideration must be given to developing new strategic policies relating...
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,...
