Building Structures
This volume contains over forty papers from thirteen sessions of Structures Congress '87. The papers include a variety of topics on the overall behavior and design of buildings...
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...
Application of Satellite Remote Sensing for Identification of Irrigated Lands in the Newlands Project (
As one element of Operating Criteria and Procedures for the Newlands Project in west-central Nevada, the Bureau of Reclamation has compiled an irrigation water rights spatial data base....
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,...
Going Sewerless
An in-building wastewater recycling system is an option where lack of sewers, limits on water supply, and special concerns about water quality are obstacles. The system was incorporated...
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,...
A Stochastic-Conceptual Reservoir Inflow Forecasting Model
The development of a method to improve real-time forecasting of reservoir inflows for the purpose of minimizing water loss through spillage is presented. Streamflow forecasts are computed...
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...
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...
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...
Monitoring Techniques for Thermosyphons
Two-phase thermosyphons used for passive soil refrigeration are monitored using a variety of techniques ranging from visual infrared scanning to measurement of internal pressures. Methods...
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...
Ice Cover Research?Present State and Future Needs
Presentation reviews, at first, a number of problem areas in ice engineering, such as the determination of vertical and horizontal forces floating ice covers exert on fixed structures,...
Wastewater Plant Cold Weather Operational Problems
A questionnaire survey was conducted at biological wastewater treatment facilities in northern New England. Problems associated with various unit processes, due to cold weather operations,...
Repair Welding of Arctic Offshore Structures and Vessels
This paper describes the welding procedure development for repair or field modifications of offshore drilling structures and vessels made with several different steel grades produced for...
