Design and Construction of Paute Project, Ecuador
The Paute Project is a key element in Ecuador's program for developing a modern electric power system. When fully developed, it will consist of three separate developments:...
Efficient Small Hydroelectric Plant Operation
This paper presents a review of operating and maintenance alternatives for small scale hydroelectric plants. The cost of operating a hydro project is largely determined by decisions made...
Steel Poles?Past, Present and Future
When using steel pole structures, construction possibilities are limitless. Of all the options available, tubular steel structures provide the most versatility for transmission line construction....
Innovations in Prestressed Concrete Structures
Prestressed concrete poles are probably the best choice for most transmission line structures. They have many advantages over structures made from other materials for both engineering...
Special Pile Foundations for a Coastal Permafrost Site
The design of the plant's foundations had to address several challenging geotechnical conditions. These included (1) 'warm' (close to 32 degree F)...
Survey of Airport Pavement Distress in Cold Regions
The most common pavement problems were associated with non-traffic related phenomena and included pre-existing cracks reflecting through asphalt concrete overlay (in two years or less),...
The CBR Test Applied to Processed and Compacted Snow
The processes used during the past two decades to improve the snow bear a modest resemblance to conventional flexible pavement construction, thus the field CBR (California Bearing Ratio)...
Design of Modular Structures for the Arctic
Sohio's efforts to continue the production and initial processing oil from Prudhoe Bay, Alaska requires additional production enhancement equipment on the Alaskan North Slope...
Snow Load Design for Colorado Mountains
During the past decade, Colorado mountain construction has experienced a period of rapid growth. New ski resorts and other business developments have resulted in many new facilities. For...
Anchorage Taps Eklutna Lake for New Water Supply
The 170 million Eklutna Water Project will furnish water to Anchorage, Alaska by the summer of 1988. The project consists of an 8,500-foot long diversion tunnel, 6 miles of 54 to 60-inch...
Alyeska Reroutes Trans-Alaska Pipeline at MP 200
This paper discusses the 1985 wintertime repair/reroute to the Trans Alaska Pipeline System (TAPS). The rerouted pipe was approximately 4000 feet long and cost approximately 27 million....
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...
Waterfront Stabilization Project, Kaktovik, Alaska
This paper discusses an innovative 384-foot treated-timber cribwall design utilized to control rapidly accelerating thermal erosion and establish a roadway along the bluff on the Beaufort...
Legal Concerns in Cold Regions Engineering and Construction
For a variety of reasons the potential for the imposition of liability and the potential for comparatively large damage claims is greater in cold regions. It is the purpose of this paper...
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...
Optimal Design of Continuous Prestressed Concrete Girders
Design of continuous prestressed concrete girders with possibility of parabolically varying depth in each span is formulated in the form of a mathematical programming problem. The design...
A Microcomputer CAD System for Seismic Design of Regular Highway Bridges
A microcomputer program to implement the recent seismic design guidelines for highway bridges is described. The methodology was developed by the Applied Technology Council (ATC) and is...
Nonlinear Analysis of External Prestressed Bridges
Finite element formulations for analysis of the overall response of concrete bridge girders prestressed with external tendons is described. The analytical procedure includes several nonlinear...
Analysis of R/C Slab Under Turbine Missile Impact
Turbine missile impact on reinforced concrete barrier in nuclear reactor power plants is simulated using the finite element method. One of four full scale turbine missile impact tests...
