Connecticut: A Success Story
The Connecticut Department of Transportation (ConnDOT) had warned the state legislature that its highways and bridges would continue to deteriorate without increased funds for inspection,...
Tunnel Saved by Flyash
When inspection early in 1986 showed that Detroit's Northeast Raw Water Tunnel was near collapse at one location, quick action and a unique use of flyash-cement grout or fill...
Fail Safe Management
Engineers are increasingly embroiled in cases where failure is defined as improper administration or management of a procedure instead of the collapse of a structure or the failure of...
Artist in Wood Structures
Julius Natterer is chairman on the Institute for Wood Structures at the Federal Institute of Technology in Lausanne, Switzerland, and designer of more unusual or unique wood structures...
Concrete Strength Record Jumps 36%
A Seattle building now going up has 19,000 psi concrete, the strongest ever in conventional structures. It costs three times as much as conventional concrete, so will not be widely used....
Instant Jails
Prison planners are responding to the explosion in the prison population by stepping up construction of new jails. Because of the pressures imposed by court ordered deadlines, engineers,...
Journal of Cold Regions Engineering
The Journal of Cold Regions Engineering publishes practice- and research-oriented articles from any area of civil engineering that is substantially related to cold regions. Topics include ice engineering,...
Journal of Performance of Constructed Facilities
The Journal of Performance of Constructed Facilities attempts to improve the quality of the constructed product through interdisciplinary communication. Papers examine the causes and costs of failures...
Small Hydro Technology Transfer Project: Licensing Activities
This paper summarizes a report that is part of the Small Hydro Technology Project, sponsored jointly by the Department of Energy and the Electric Power Research Institute (EPRI). The Licensing...
Design Criteria for Generators in Low-Head Hydro-Power Plants
Principal characteristics and design features of such generators are discussed and options and preferences in their selection mentioned. Effects on inertia constant, efficiency, reactive...
Changing Stability Criteria: Effect on Older Dams
Many of the dams on the Georgia Power Company system were designed and constructed in the early 1900's. Changes that have occurred in stability criteria since construction...
Rehabilitation of Victoria Dam
Rehabilitation of a 54-year old thin concrete arch-buttress dam was completed without interruption of power generation using pressure injection of an epoxy adhesive. This paper presents...
Synopsis: Ozark-Webbers Falls Turbine Repairs
The Ozark and Webbers Falls powerhouses were designed and constructed under the supervision of the U. S. Army Corps of Engineers and are located on the McClellan-Kerr Arkansas River Navigation...
Strain Gaging and Data Acquisition at the TLMRF
Strain gages are the major source of data for the TLMRF (Transmission Line Mechanical Research Facility) research program. Measurement of member loads and bending moments in lattice towers...
Adfreeze Strength of Ice to Steel Pipe Piles as a Function of Temperature
A study was initiated to determine the adfreeze bond strength between steel pipe piles and freshwater ice as a function of temperature. Tests were conducted at an average strain rate of...
Costs of Truck Related Highway Damage to Alaska
The cost of pavement damage to the State of Alaska for truck traffic continues to be a very controversial topic. There is no simple answer since this cost is dependent upon pavement strength,...
The CBR Test Applied to Processed and Compacted Snow
The processes used during the past two decades to improve the snow bear a modest resemblance to conventional flexible pavement construction, thus the field CBR (California Bearing Ratio)...
Soil Strength Recovery Using a Clegg Impact Device
The research described in this paper uses the Clegg Impact Device to determine the relative strength of a soil, and describes how this information can be used to develop the strength recovery...
Testing of Admixtures for Seabed Strengthening
Samples from several offshore soil borings in an area of the Beaufort Sea were subjected to laboratory testing to determine the applicability of this method. The soils were mixed with...
Ester West Slide?A Case History
An 80 foot high embankment was benched into graphitic schist permafrost on a north facing slope approximately 25 miles west of Fairbanks, Alaska. Soon after construction approximately...
