Committees of the American Society of Civil Engineers have been in the forefront on updating design guides to address improved procedures for conventional latticed towers, formed-plate...
Longitudinal Impact Loading of Transmission Towers
A scale model has been developed to study a containment failure design concept for longitudinal (along the direction of the conductor) impact loading of electrical transmission structures....
Limit State Analysis Correlated to a Full Scale Tower Test
A Limit State analysis technique has been developed for evaluating the structural capacity of lattice steel electrical transmission towers. The tower strength is determined by using a...
Variation in Design Practice for Lattice Towers
The design and analysis procedures employed for lattice transmission towers vary among countries, companies, and designers. This variation in design practice affects the relative reliability...
New Outlines for 500 kV Transmission Towers Using Cold-Formed Shapes: The Experimental Line of the American Electric Power Research Institute
The use of cold-formed steel members, in electrical transmission towers, is actually a feasible, reliable and economical solution. The EPRI experimental line is an example of the newest...
Modular Restoration Structures?A Versatile and Cost Effective Transmission Tool
Most electric utilities use a large variety of different types and designs of transmission structures. Because of this, it is not practical or economically justifiable for these utilities...
Parametric Study of Bracing in Lattice Towers
The behaviour of cross-bracing comprising struts and ties connected at their cross-over joints in lattice towers is subject to some uncertainty. It is affected significantly by taper and...
Reliability-Based Design of Transmission Line Structures
Reliability-Based Design (RBD) is an emerging concept for the design of transmission line structures and holds the potential to reduce the cost of lines or increase their reliability....
Containment Model ? Test Program and Results
Sandia National Laboratories (Sandia) completed the testing of a 1:6-scale containment building for a Light Water Reactor (LWR) in July 1987. The containment building was made of reinforced...
Full-Scale Measurement on Chiba Port Tower
Chiba Port Tower is a tall tower, 125m high, with a rhombus shaped plan. All of the surfaces are covered with half mirror glass. On the top of the tower, a 'Tuned Mass Damper'...
Vibration-Induced Wind Pressure on Large Span Flat Roof
Vibration-induced wind pressures on a large span flat roof was investigated by a wind tunnel using a uniformly turbulent flow. Measurements of pressures were made on an asymmetrically...
Wind Resistant Design Manual for Highway Bridges
The new wind resistant design manual for highway bridges has been required recently in Japan. The working group was organized in the Japan Road Association is 1984 to prepare the manual....
Instrumentation of the Shenyang T.V. Tower
The recently-completed Shenyang radio and television tower provides a unique opportunity to obtain comprehensive measurements of the along-span variation and coherence of wind-induced...
Characteristics of a Structure-Foundation System
The dynamic characteristics of the structure-foundation system of a 1/4 -scale nuclear power plant containment model is studied using seismic records. The model structure is treated as...
Seismic Isolation of Nuclear Plants: A World Overview
The French were first to apply seismic isolation to the design of nuclear structures. Two large Pressurized Water Reactor plants (PWR) were isolated; the two unit Koeberg station in South...
Assessment of Transmission Line Foundations
Electric utilities are faced with the need to build new transmission lines or to upgrade existing lines to meet future demands. Because of economic constraints and the difficulty of obtaining...
Making Amends with Nature
The U.S. salmon population has been decimated in the last half-century, principally because of hydropower. In the nation's focus on alternate and clean energy sources, fish...
Power Pole Foundations in Reclaimed Mining Area
In central Florida, where strip mining for phosphate ore is a primary industry, street surfaces often become rolling because of differential settlement, and electrical transmission poles...
CUFAD: A Computer Program for
A research effort within the electric utility industry has focused on unified design methods for axially loaded foundations for transmission line structures. This research has been made...
Selection of Marine Bioindicators for Monitoring Radioactive Wastes Released from Nuclear Power Plants
