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),...
On the Constitutive Behavior of Single Ice Crystals Due to Dislocation Mechanisms
A three-dimensional constitutive relation is derived for single ice crystals. The formulation is developed in terms of dislocation processes on the basal, prism, and pyramidal planes....
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...
Size Effects in the Fracture of Quasi-Brittle Materials
Causes and influences of the structural size effect that is exhibited by materials such as concrete, mortar, ice rock and ceramics, are discussed. The size effect law, which models this...
Some Questions on Fracture Mechanics of Ice and Ice Covers
Investigation of natural processes of deformation and fracture of ice covers, and processes of its interaction with icebreaker or ice-resistant structures requires as a rule considerations...
Effective Pressures Measured During Indentation Tests in Freshwater Ice
Indentation tests were conducted by pushing flat, vertical indentors of two different widths (50 and 100 mm) against the edges of floating, freshwater ice at different velocities (0.6-150...
Wind Tunnel Modeling of Time-Dependent Drift Topography
The aeolian wind tunnel is a useful tool for investigating not only the saltation physics of wind-driven sand, soil or snow, but also for determining the time-dependent development of...
Tomorrow's Toll Road
Techniques using automatic vehicle identification (AVI) currently provide the most efficient form of electronic toll collection. Several systems have been installed in the U.S. in the...
Precipitator Retrofit and Repair: A Case Study
Described is a difficult fossil power station retrofit project performed on a tight schedule at a congested site. Installation of a new supplementary precipitator and structural repairs...
Designing for Corrosion Control
This presentation will discuss designing from several aspects: a. Designing of the item to lessen the affects of corrosion. b. Selection of non-corrosive materials in the designing process...
The Changing Legal Structure of Non-Utility Generation in the 1990's
Before actual construction of a small power production or cogeneration facility commences, numerous economic, technical and legal factors have been considered during the planning process....

Approximate Methods of Structural Analysis: Principles and Pitfalls
In this modern age when the trend in structural engineering and structural engineering education is to make more and more use of computers and standard structural analysis programs, there...
Wind Frame Design for Mid Rise Buildings
A brief discussion of drift limits is followed by design procedures for unbraced moment resisting wind frames and initial selection of optimized member sizes for chevron bracing frames....
Analysis and Design of Structures with Outrigger Arms
Although sophisticated computer methods are available for analyzing an entire building structure, there is a need for simplified methods (a) for checking the accuracy of the computer analyses,...
Multiple Event Considerations for Postclosure Seismic Hazard Evaluations at Yucca Mountain, Nevada
Postclosure waste canister design requirements suggest the values used for seismic design have less than a 10% chance of being exceeded in a 1,000 year postclosure period. Considerably...
