Infrastructure Awareness: Successful Techniques
The need to rehabilitate and upgrade our infrastructure systems, specifically the systems of water supply and distribution, wastewater collection and treatment, bridges, highways and mass...
Learning From Failure
Innovative engineering design involves assumptions about the future use and behavior of a structure. By understanding and learning from the infrequent but spectacular large failures, engineers...
Frame Moments with the Takabeya Method
The Takabeya method of frame analysis, based on the same slope-deflection equations as the Hardy-Cross system, has the advantage of requiring much less memory and fewer computations than...
Rationalizing Land Records, Mapping, Planning
The way land records are kept and used in cities and counties is outmoded. The same is true for base mapping and land use planning. The computer is helping streamline all three, as is...
A Critique of Arctic Marine Site Investigation Techniques
Arctic marine site investigations have evolved from the need by oil companies to operate in offshore areas beyond the ice shear zone. An overview of the site investigation organization...
Electrical Resistivity Techniques for Offshore Arctic Geotechnical Engineering Applications
The electrical resistivity of an arctic marine soil depends on the porosity, pore water salinity, grain size and shape, clay content, and degree of ice-bonding of the soil. Therefore,...
NPDES Permits for Accelerated Oil & Gas Development
Section 402 of the Clean Water Act (CWA) requires the Environmental Protection Agency (EPA) to develop National Pollutant Discharge Elimination System (NPDES) permits for waste discharges...
Environmental Permitting Approaches for Future Development of Offshore Oil Fields in the Arctic
Environmental impact of petroleum prospecting on the North Slope of Alaska is complicated by climatic problems of long periods of low temperature and thick ocean ice. Better engineering...
Creep Properties of Ice: Theory and Experiment
In recent years, intensive developments in Northern regions have increased the demand for solutions to a large number of engineering problems involving ice mechanics. In particular, these...
Triaxial Compression Testing of Ice
An understanding of the confined compressive strength of ice is needed to develop constitutive equations and failure criteria for analytical ice-structure interaction models. Procedures...
Arctic Earth Materials for Offshore Construction in Alaska
With the exploration activities onshore and offshore and the development of production facilities, the need for granular earth materials on the North Slope of Alaska is ever present. The...
Geotechnical Thermal Analysis with a Microcomputer
A computer program entitled TDHC (Two-Dimensional Heat Conduction), based on finite element modelling, is capable of solving two-dimensional nonsteady-state heat conduction problems. These...
Orthophotoquad Mapping Program for Alaska
The U. S. Geological Survey (USGS) is the lead civilian mapping agency in the United States and is responsible for creating and maintaining numerous map series. In Alaska the standard...
Constitutive Equations for Ice as a Damaging Material
Constitutive equations for ice subjected to uniaxial compression are developed based on applications of the theory of continuous damage mechanics. A physical model of ice deformation response...
A Hybrid Structural Ice Defense Mechanism
A hybrid plate composed of steel outer surfaces and a concrete core has characteristics that make it desirable for use on offshore structures in ice prone environments. The service and...
Research Needed for Civil Engineering in the Arctic
A survey is based on the work of the Research Committee of the ASCE Technical Council on Cold Region Engineering and findings in a number of previous reports on research needs in cold...
Geotechnical Design of Caisson Islands
There are a number of areas where fundamental geotechnical research is required so that non-conservative, rational and safe design of artificial exploration islands can be achieved. Some...
Arctic Offshore Engineering: A New Graduate Course at Texas A&M University
Based upon the present projections for the offshore petroleum industry, many of our future engineering graduates will find employment related to Arctic Offshore activities. In an effort...
SAV Reestablishment Results?Upper Chesapeake Bay
In the Susquehanna Flats area of the upper Chesapeake Bay, six submersed aquatic plant species were used to test the feasibility of transplanting SAV into sites which were previously vegetated,...
Multi-Truss Design for Tower
A modified structural steel system of outrigger trusses and belt trusses bolster the 54-story Equitable Tower West. Located in New York City, the building's structural system...
