Structures Congress '92
Compact Papers
These Congresses provide a forum for the practicing engineers, researchers and educators. The involvement of numerous ASCE Divisions has helped to create a program that will appeal to...

Journal of Professional Issues in Engineering Education and Practice
The Journal of Professional Issues in Engineering Education and Practice presents issues of broad professional interest and diverse views of engineering education, and professional practice. Papers examine...

Safety Factors, Loads, and Impact
The loads given in this chapter are intended for general guidance only (including wind, ice, stream flow, etc.). Maximum deflections and rotations may likewise vary with national codes....

Cellular Sheet-Pile Floodwall
Williamson, W. Va., flooded 37 times in this century, will soon be guarded by a $41 million, 4000 ft floodwall being built by the U.S. Army Corps of Engineers. A series of 41 circular...

Ownership Transition: Planning for Pitfalls
The transition of a company's ownership can be a crisis caused by the retirement or sudden death of a company's owners, or an event planned for well in advance....

Laboratory Methods for Preparing Low-Density Frozen Saline Soil Samples
Laboratory methods were developed for preparing low-density frozen saline soil samples with density values ranging from 85-110 lb/ft3. This range...

The Effect of Loading Rate on the Bending Strength of Alluvium Reinforced Ice
Traditional building materials are often less than ideal for construction in remote Arctic locations. Their mechanical properties may be degraded in extreme cold, and costs associated...

Water Conservation at the Antarctic Wasa Base - Results 1989-90
The Swedish WASA base was erected in the Norwegian sector of Antarctica during the 1988-89 summer season. The base was on a nunatakk and consisted of a dwelling house with full living...

A Wetlands Sewage Treatment System for the Community of Teslin
The Village of Teslin, with a population of 450, is located in south-central Yukon, approximately 180 km southeast of Whitehorse. Since 1977, the community has been trucking its sewage...

Sludge Dewatering in Freezing Beds
This paper summarizes the results of laboratory and pilot scale studies on the development of the sludge freezing bed. Laboratory studies indicated that a freezing bed could dewater up...

Numerical Analysis of Frost Shields
The term 'frost sheilding' has been used to describe the practice of using flat stock rigid insulation materials burial above a water or sewer pipe to reduce...

New Admixtures for Cold Weather Concreting
Chemicals were tested for their ability to promote strength gain in portland cement concrete at low temperature. The admixtures depressed the freezing point of the mix water and accelerated...

High-Performance Concrete in All-Weather Deck Pours
A high-performance concrete mix enhanced with a combination of microsilica, superplasticizer, and high dosages of an corrosion-inhibiting, accelerating admixture (calcium nitrite); proved...

Cold Climate Building Research at Wasa Base, Antarctica
During the Antarctic summer season of 1988-89 a permanent Swedish research station was erected at Dronning Maud Land, Antarctica. The station, named Wasa, is situated on a nunatak. A corresponding...

The River Ice Management (RIM) Program: Developing New Options for Waterways Operations in Winter
Most of the navigable inland waterways of the United States are utilized year-round. In northern portions of this network (mainly parts of the Ohio and Upper Mississippi River basins),...

Minnesota Road Research Project - An Overview
The Minnesota Department of Transportation in cooperation with the Federal Highway Administration and the Local Roads Research Board of Minnesota is constructing the Minnesota Road Research...

Visco-elasticity and the Compressive Failure of Polycrystalline Ice
The analysis of the visco-elasticity of polycrystalline ice is addressed. Experimental results on isotropic and anisotropic polycrystalline ice are presented, which indicate that intracrystalline...

Anelastic Straining in Polycrystalline Ice
This paper presents experimental observations on the influence of stress, grain size and total strain level on the magnitude of anelastic strain in granular freshwater ice. Cyclic loading...

Microstructure and Mechanical Behaviour of Ice
Short descriptions are given for ice in nature, test methods used to evaluate their deformation behaviour and, a general microstructure-based constitutive equation. Equations suitable...

Fractal Crushing
This paper develops an approach to a two-dimensional fragmentation process, in which floating ice floes are driven against each other and break up into smaller floes. It first considers...
