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...
The Electric Power Research Institute's TLWorkstation?
The initial version of the Electric Power Research Institute's TLworkstation software system is described. The factors influencing the software design and the programming...
Demands for Innovation in Power Construction
This paper identifies some specific demands for innovation on power projects, reviews the alternatives considered to meet project objectives, and describes the resulting innovations. Examples...
Engineering Implications of Impoundment of the Indus River by an Earthquake-Induced Landslide
Historical records and physical evidence indicate that in the Himalayas of northern Pakistan a huge landslide dam was caused by an earthquake in 1840. The dam blocked the Indus River,...
Professional Training Potomac Electric Power Company (PEPCO)
Training of professionals within the Generating Engineering and Construction Group at the Potomac Electric Power Company is most intensive right after hiring but continues to the executive...
Base Isolation in the Design and Construction of Power Plant Structures
This technical paper summarizes the results of some of the recent studies performed to assure technical feasibility in isolating safety-related nuclear power plant structures. The particular...
Design and Planned Use of a 2-Kiloton Eccentric Mass Vibrator
High-level testing of large civil structures is usually not practical, due to structural damage considerations and available testing equipment. However, in the case of a joint American/German...
The Atlantic Palace?Part II The Application of Wind Tunnel/Force Balance Techniques
A relatively new approach for determining overall wind-induced loads on a structure is described. This force balance technique is economical and flexible, and able to provide predictions...
Structural Settlements at a Major Power Plant
The foundation design for the Intermountain Generating Station was based on comprehensive geotechnical investigations that included cone penetrometer tests, borings, pressuremeter tests,...
