U.S./PRC Cooperation on the Three Gorge Project
The Three Gorge Project is the keystone project in developing and using the Yangtze River. It is located on the main stem of the Yangtze River, about 40 km upstream from the Gezhouba Project...

New Runners for Aswan High Dam Power Station
Replacing turbine runners at Egypt's Aswan High Dam Power Station is a major project because of the size, quantity and importance of these turbines to the Egyptian economy....

The Impact of Proposed Federal Income Tax Changes on the Financing of Hydroelectric Projects
The paper presents an overview of the specific proposed changes that would have the greatest direct impact on the hydroelectric power industry. Next, it presents the major conclusions...

LRFD Format for Transmission Structures
The structural design of high voltage electric transmission lines in the US is usually governed by the National Electrical Safety Code (NESC). A simple reliability-based Load and Resistance...

Wind Loads on Electrical Transmission Structures
Guidelines for structural loads on electrical transmission structures were prepared by the American Society of Civil Engineers' Committee on Electrical Transmission Structures....

A Field Study of Wind-Induced Conductor Loads
A 161 kV steel pole line in Omaha, Nebraska, is instrumented to provide conductor load field data due to climatic events. Various transducers and monitoring equipment used for data acquisition...

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....

Lattice Tower Design Using Cold-Formed Shapes
The use of cold-formed shapes in lieu of hot-rolled angles may lead to major changes in the design of lattice transmission towers. The design procedure of the new shapes is more creative,...

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...

Cold-Formed Angles for Transmission Towers
Cold-formed members enable the engineer to design transmission towers that may be more cost-effective than those built with hot-rolled angles. Members can be designed to closely fit the...

Design and Test of Cold Formed Steel Members
Latticed systems represent the most spread and low-cost solution for electrical trasmission towers, when ground conditions do not affect the design choice. Steel angles have been used...

Bolted Connections for Steel Towers
Laced electrical transmission towers require on-site assembly. Consequently, the number of bolts and pieces are important considerations in the total cost of the structures. ASTM A394(1)...

IEEE/ASCE TransmissionStructure Foundation Design Guide
The American Society of Civil Engineers' (ASCE) Subcommittee on Foundation Design for High-Voltage Transmission Structures was formed in October 1976. The purpose of the Subcommittee...

TLMRF Research Initiatives
The research initiatives of the EPRI (Electric Power Research Institute) structural development project RP2016-03 are described. The interrelationship of these initiatives with cosponsored...

Strength Data Base for LRFD of Transmission Lines
Reliability-Based Load and Resistance Factor Design (LRFD) has been proposed as a desirable alternative or a complement to the National Electrical Safety Code (NESC) for the structural...

A Self-Refrigerated Gravel Pad Foundation for Large Thermal Loads
Design criteria for a proposed power plant at Thule Air Force Base, Greenland, involved both large thermal loads from the diesel engines and large static loads from an eight foot thick...

Development of a Self-Heating Thermal Probe for Saline Permafrost
Geothermal modelling and prototype testing are described to support the development of a self-heating thermal probe. This has application for in-situ determination of the amount of unfrozen...

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...

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...

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...
