Aseismic Calculations for Transmission Towers
In this paper, mechanical models for long-span transmission line systems under elastic and gravitational restoring forces are established in three different directions; this continues...

Reliability of Overhead Transmission Lines Subjected to Wind Action
The probability distribution of the strength of steel towers used in transmission lines, due to wind excitation, is evaluated on the basis of test results of 72 towers of various designs,...

Fully Nonlienar Models to Simulate Structural Response to Wind Loading
The paper summarizes some results of the analyses of two tall broadcasting towers, obtained by means of a specially developed numerical procedure taking into account all relevant nonlinear...

U.S. Landmarks: Handle With Care
Landmarks are treated with kid gloves during restoration, but striking a balance between costs and aesthetics is difficult. In addition to structural integrity, original construction methods...

Composite T Beam Bridge Deck on Timber Towers

Improved Techniques for Assessing Structures
The Electric Power Research Institute (EPRI) has specially designed and equipped the tower testing station located within their Transmission Line Mechanical Research Center (TLMRC) near...

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...

Early Age Strength Detection for In-situ Concrete
In recent years it has become increasingly beneficial to know the quality of concrete as soon as possible after it has been placed. This is especially true for high-rise concrete buildings...

Wind Tunnel Testing of the Karnali River Bridge
An extended wind tunnel testing program of the erection procedures and the stability of the completed one-tower cable-stayed Karnali River Bridge was conducted with the help of full bridge...

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...

Structural Analysis of Guyed Antenna Towers with Compression-Torsion Coupling

Classic Wood Structures
Wood has been used in a wide range of structural applications. When properly maintained, these structures can have a useful life from 50 years to several centuries. Thirty-seven unusual...

Burlington Cable-Stayed Bridge
The Burlington cable-stayed bridge will carry US34 over the Mississippi River from Burlington, Iowa to Gulfport, Illinois. There will be two 12-ft lanes in each direction plus an acceleration...
