Evaluation of Combined Load Tests of Prestressed Concrete Cylinder Pipe
Combined load tests of prestressed concrete cylinder pipe, presented by Tremblay in the proceedings of this conference, are analyzed. Data gathered during the tests includes first visible...
Analysis of Alternative Pipe Materials for a Major Public Water Agency
A major southwestern public water agency has historically specified the exclusive use of prestressed concrete cylinder pipe (PCCP) for large diameter water transmission mains. Due to the...
Twin Pipeline Crossing of the Fraser River
A new creek water supply was developed for the communities of Mission and Matsqui, British Columbia, Canada, in the early eighties. Over 60 kilometres of 450 mm to 900 mm diameter ductile...
Relining of Jordan Aqueduct, Reach 3
As pipelines approach their life expectancy, they may need to be replaced. Or in some instances, replacement is needed much sooner due to defective pipe. Normal replacement operations...
Less Bang for the Buck
Blasting rock is practical on job sites with ample space, but on construction sites in urbans or developed settings, contractors are shying away from blasting for several reasons. Noise...
Creative Connections: Bridges as Art
Princeton University professor of civil engineering David P. Billington, at the invitation of civil engineering professors at Tokyo University, tours Japan and critiques several of the...
Concrete Cask Storage Technology
The paper presents the design and operation of the new dry storage system for nuclear waste. The system was designed by complete nuclear, thermal-hydraulic and structural analysis to the...
A Cost Study of Concrete Production on the Moon
In proposing and evaluating a construction system for a lunar base, the question of cost would be the most important one. Although it is not possible to conduct a detailed cost study at...
Soft Bottom Low Flow Channel?A New Approach
In 1987, the City of Boulder, Colorado requested assistance from the Urban Drainage and Flood Control District (District) to repair a problem of cattails growing in the low flow portion...
Creede, Colorado?Channel Rehabilitation
The existing grouted stone channel in Creede, Colorado, is approaching the end of its useful life. The channel is subjected to repeated freeze-thaw cycles causing spalling of the grout...
The Impact of the Morris Sheppard Dam Experience on Buttress Dam Safety Evaluations
The stability problems encountered at the Morris Sheppard Dam have had an impact upon the Federal Energy Regulatory Commission's (FERC) dam safety program. This paper describes...
A Knowledge-Based Approach to the Design of Highway Bridge Foundations
This paper discusses the development of a prototype expert system using a commercially available expert system shell. The system is to be used for the selection of highway bridge foundations....
A Bridge Management System Module for the Selection of Rehabilitation and Replacement Projects
A procedure, developed for the state of Texas is reported, which determines an allocation budget for bridge replacement and rehabilitation projects, using multi-attribute criteria and...
A Microcomputer Aided Bridge Management System
This paper presents a microcomputer based software system suitable for a local agency which will permit a local bridge system to be systematically evaluated with the use of a bridge management...
Concrete Pipe Trenchless Technology
Precast reinforced concrete pipe is the most commonly used pipe material for jacking operations. For over 90 years, concrete pipe techniques, procedures and applications established the...
The Great American Pyramid
For more than 50 years officials of Memphis, Tenn. have wanted to establish a link to their Egyptian namesake--and they will, through a pyramid. As opposed to its Egyptian forerunners,...
Florida Bridges Beat the Clock
Today, when budget overruns and delays on construction projects are the rule more than the exception, 11 precast segmental balanced cantilever bridges on two contracts were recently completed...
On the Drawing Board
Reliable and quantitative nondestructive evaluation (NDE) methods for construction materials of wood, concrete, masonry and structural steel are needed. NSF program director John Scalzi...
Bridges Under Surveillance
Although bridge monitoring is still in its infancy, research, pilot studies and field work are underway across the country. While today it's still a pie-in-the-sky goal, the...
Northumberland Strait Crossing Project?A Public-Private Venture
