A Thermal Analysis of Pavement Thawing
This research focuses on identifying the spring thawing period for the purpose of timing load restrictions on low to medium volume roads in frost-susceptible areas. Cases evaluated include...
Terrain Analysis From Space Shuttle Photographs of Tibet
Several Space Shuttle missions obtained false color and large format, high resolution, black and white stereo photography at an approximate scale of 1:800,000. In addition to available...
An Overview of Cold Region Considerations for the Design of the Eklutna Water Project
The paper presents a brief overview of cold regions considerations that were considered during the design of the various elements of the Eklutna Water Project in Anchorage, Alaska. The...
Massive Ice Detection by Earth Resistivity
This paper presents two case histories utilizing remote sensing earth resistivity equipment to target subsurface massive ice locations. In one case, a number of probe locations were made...
Finite Element Modelling of Cold Regions Concreting
Finite element heat transfer computer programs are discussed in regard to their use in modelling cold weather concreting. The concrete material properties required for input to the finite...
F.E.M. Analysis of Mobile Arctic Caisson Island With Stochastic Material Properties
The paper examines how soil uncertainty influences the short term settlements and stresses of the Mobile Arctic Caisson on the original sea bed. Utilizing a two-dimensional plane strain...
Moisture Effects on Extruded Polystyrene Insulation
The amount of moisture within the insulation was determined by carefully weighing each sample and then measuring its volume. Two methods of measuring thermal conductivity were used. The...
Proposed Operation of an Expert System for Analyzing Construction Project Risks
The principal problem for the construction project manager is selecting the most effective response when project progress deviates undesirably from targeted objectives. Optimally, the...
Finite Element Analysis of Concrete Armor Units Subject to Wave Impact
Concrete armor units are commonly employed for the protection of shorelines and rubble structures. Their design is primarily based on hydrodynamic stability. However, their structural...
Sheet Pile Interlock Behavior: A Moving Contract Problem
The finite element method is used to analyze the behavior of sheet pile interlocks subjected to an uniaxial pull test. The thumb and finger of the interlock provide three contact points...
Broke2: A Program for Broken Wire Analysis
A computer program to study the dynamic behavior of an electric transmission line system when wires suddenly break has been developed by the authors. All three of the line elements: the...
Spring Stiffness for Beam-Column Analysis of Soil-Structure Interaction Problems
The objective is to provide a simple means of analytically combining a two-dimensional foundation with a beam-column structure so that the procedure can be used for preliminary design...
Dynamics of Machine Foundation
The art of designing machine foundations, supporting vibratory load has changed from the approximate rule-of-thumb to the scientifically sound engineering procedure. However, the vast...
