Offshore Platforms Subjected to Wave Forces
The dynamic analyses of offshore platforms are mostly based on the lumped mass matrix method in the frequency domain. Although the approximations involved in the lumped mass matrix method...
Explosive Loading of Surface Ships
This paper describes the recent development of numerical methods which have accurately predicted the response of surface ships subjected to underwater explosion tests. The technique couples...
The Effects of P-Delta and Semi-Rigid Connections on Response Behavior of Inelastic Steel Frames Subjected to Cyclic and Seismic Loadings
A numerical method is presented for analyzing semi-rigid connected steel frames subjected to various time-dependent excitations with consideration of damping, nonlinear material behavior...
The Ultimate High Tide
Unprecedented consumption of fossil fuels and clearing of vegetation have spurred interest in the greenhouse effect. Under this scenario, a build-up of carbon dioxide and other gases in...
Structural Applications of SIFCON
SIFCON (Slurry Infiltrated Fiber CONcrete) is a relatively new composite material utilizing steel fibers in a cement-based matrix. It differs from conventional steel-fiber-reinforced concrete...
Behavior of Concrete Bulkheads in Salt Drifts
Parameters studies of the behavior of a plug made from expansive concrete have been performed. Such plugs are now being field tested for sealing boreholes, shafts and drifts at an underground...
Influence of Surface Conditions on Surface Temperature
Geotechnical engineers working in areas of discontinuous permafrost are frequently faced with the necessity of designing facilities with a minimum of thermal disturbance. Construction...
Nonlinear Analytical Models for Interfacial Plug Stresses in Creeping Salt Formation
Analytical and numerical simulation models are presented which predict the nonlinear time dependent behavior of an expanding plug in a creeping environment heavily dependent on the storage...
Design of Impact Limiters for Waste Fuel Shipping Casks
Impact limiters are often used to control the decelerations experienced by a waste fuel shipping cask when it is subjected to the hypothetical accident condition loadings. Simplified design...
Geotechnical Data Acquisition and Computerized Analysis
In 1983 and 1984, an exploratory tunnel was constructed as part of the geotechnical exploration program for two highway tunnels to be constructed for the improvement of Interstate 70 through...
Effectiveness of Erosion Control
Erosion control in the urban environment is addressed from the perspective of the mechanisms of erosion. The primary cause of erosion in urban areas is flowing water. Measures are identified...
Detention and Retention Controls for Urban Runoff
The operating principle for retention devices is the interception and capture of runoff, preventing its direct release to surface waters. The most common mechanism by which captured runoff...
Global Water Issues
Five critical global water-related issues are discussed. First is the issue of climatic changes and drought. Unfortunately, the opportunities to construct major irrigation projects are...
Cut-and-Fill Becomes Cut-and-Drain
The U.S. Navy's facility in Subic Bay, Philippines, is in a mountainous area which experiences 182 inches of rain per year. These factors plus weak soil, made necessary an...
Research on Transportation Facilities in Cold Regions
Transportation facilities research in cold regions, reported in this session proceedings, begins with a field study showing that ground surface characteristics have a significant effect...
The National Infrastructure Act
Today, more than ever before, the United States faces a serious problem related to the condition and adequacy of its basic infrastructure - surface transportation, water supply and distribution,...
Concrete Quality Control and Quality Assurance on Strontia Springs Dam
An essential part of the construction management services provided on Strontia Springs Dam was the quality control of material, mixture proportions, and production for all concrete placed...
Determining Soil Properties by Electric Cone Penetrometer
Gravel island construction is one primary means of establishing permanent locations for oil wells, building foundations and road beds in the arctic. The gravel provides a natural insulation...
Soil Strength Determinations from the Cone Penetrometer Test
Geotechnical exploration in offshore Arctic regions often relies upon the electric Cone Penetrometer Test (CPT) because of its speed, economy, data continuity, and general reliability....
Iceberg Interactions with Offshore Structures
Various aspects include the component problems corresponding to iceberg drift in open water, iceberg drift in the vicinity of a large offshore structure, wave-induced motions of a berg,...
