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...

Composite T Beam Bridge Deck on Timber Towers

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...

Quincy Bayview Bridge—Construction Control
A cable-stayed bridge crossing the Mississippi River at Quincy, Illinois, was completed in August 1987. The structure includes twin concrete towers and a hybrid deck section. The cable...

Guide for Design of Steel Transmission Towers
ASCE Manual 52, Guide for Design of Steel Transmission Towers, serves as a basis for the design of both guyed and self-supporting steel transmission...

Transmission Structure Foundation Loads and Performance
Transmission line structures are subjected to unique loading conditions which for the majority of structures results in maximum loads which occur infrequently and act for only short periods...

Construction and Design of Foundations for French Overhead Power Transmission Network
This paper summarizes present conception and design of foundations for 90 to 400 kV overhead lines in France. Firstly principles of geotechnical studies in use are presented: various types...

Steel Pile Foundations for Transmission Line Towers, as Used in Western Europe

Uplift Capacity of Model Group Anchors in Sand
Small-scale laboratory experimental results for the ultimate uplift capacity of shallow horizontal circular single and group anchors embedded in sand have been presented. The experimental...

High Capacity Multi-Helix Screw Anchors for Transmission Line Foundations
Three case history summaries are presented which discuss the siting, design, and construction of towers supported on multi-helix screw anchor foundations in the Virginia Power service...

Foundations for Transmission Line Towers
This special technical publication contains the proceedings of a two session symposium on foundations for transmission line towers. These papers were written by researchers, geotechnical...

Building Over the Golden Gate
Charles Seim discusses the struggles of the original bridge advocates to garner support for the Golden Gate Bridge, an idea which originally met with a considerable amount of public opposition....

Aspects of Wind and Earthquake Dynamics of Cable-Stayed Bridges
In the course of dynamic analysis of long-span cable-stayed bridges for the effects of earthquake and wind, a number of observations have been made that may be of interest to designers....

Analysis and Design of Wind- and Earthquake-Resistance of an S-Curved Cable-Stayed Bridge
Just recently, in January of 1987, the first S-curved cable-stayed bridge in the world has been completed as a part of Metropolitan Expressway's Katsushika-Edogawa Route in...
