Interactive Bridge Optimization Program
This paper presents the development of a design methodology that includes the structural optimization process as an integrated component of girder bridge design. The optimization process...
Urban Energy Systems for the 21st Century: Transition Paths
Alternative energy systems can be expected to be a significant part of advanced, 'intelligent,' infrastructure systems for cities of the 21st Century. The question...
New Generation Capacity
Currently, electric utilities in the U. S. have excess generation capacity. In addition, some new generation capacity is well under construction and is scheduled to come on-line soon,...
Techniques for Rapid Assessment of Seismic Vulnerability
Under the impetus of a growing awareness of seismic hazards, there is an increasing effort being devoted to assessing the seismic vulnerability of existing buildings. For many professionals...
Stability Under Seismic Loading
This publication includes five papers that cover the p- ? effect on seismic structures with semi-rigid connections, the effect of panel zone deformations on the structural response behavior,...
Designing for Shock Resistance
If a product or structure is subject to shock loadings, and is unable to take them without unacceptable damage, it must be insulated from the shock. The decision may be to redesign the...
Design of Strontia Springs Arch Dam
The development of the layout and the history of design of the 292 foot (89 m) high Strontia Springs Dam is presented. While a brief description of the general project layout and foundation...
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,...
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...
Arctic Penetration Test Systems
Geotechnical exploration in offshore arctic regions relies upon the electric Cone Penetrometer Test (CPT) because of its speed, economy, data continuity, and general reliability. By adding...
The Role of Ice Gouging in Determining Global Forces on Arctic Structures
Structures built in water depths where ice keels are in contact with the seafloor can experience reductions in the environmental driving forces transmitted to structures due to seafloor...
Utilizing Design Events Within Risk-Based Design
Design load selection based on the return period of an environmental event is not possible when the event is described by more than one parameter. Risk analysis can be used to associate...
Probabilistic Design of Gravity Foundations for Arctic Offshore Structures
The use of the probabilistic simulation technique to estimate the variability of the resistance and the ice load on arctic gravity structures is illustrated in order to assess the safety...
Mini Hydro at Low Cost
The Kingsley Dam is an existing irrigation dam that has been retrofitted with electric generating capacity. The project was completed 6 months ahead of schedule without interrupting irrigation...
Modifications At Operating Nuclear Power Plants
In these days of continuing regulatory requirement changes and high interest rates, the engineering of structural modifications for operating nuclear power plants has taken on greater...
Modifying Piping Systems During a Plant Outage
This paper describes methods to reduce problems in design and planning of modifications to piping systems during a nuclear plant outage. Significant differences between original design...
Coping with Transition: Improving the Management Process
At Arkansas Power & Light Company, the Energy Supply Department has some 2,000 employees and operates (in addition to providing General Office engineering, technical, and administrative...
Project Management for the Upper Harlem Electrification Project
The Upper Harlem Electrification Project consists of a 28 mile extension of 700 V. D. C. under-running third (current carrying contact) rail electrification from North White Plains, New...
A Damage Function Using Structural Response Measurements
A new damage function is proposed that expresses seismic damage in terms of the range and number of cycles of plastic deflection experienced by a structure. This and other damage functions...
Probability-Based Load Criteria for Structural Design
Load criteria for use in limit states design of structures are developed using probabilistic methods. Statistical data on load and strengths are integrated by the reliability analysis...
