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...

Substitute Wind Concept for Elastic Stability of Cooling Tower Shells
The influence of the nonaxisymmetric wind distribution on the stability behavior of cooling tower shells is examined. It is demonstrated, considering about 50 cooling tower shells, that...

Wind Loading and Wind-Induced Structural Response
A State-of-the-Art Report
This state-of-the-art report presents fundamental and practical aspects of modern wind engineering practice as it relates to structural design. The first chapter includes information on...

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,...

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)...

Collapse Analysis of RC Shells Based on a New Fracture Criterion

In-Situ Testing to Characterize Electric Transmission Line Routes
A review of the literature has shown few definitive studies which separate test variability from soil inhomogeneity. A sensitivity study was performed to evaluate the effects of the overall...

The Response of Transmission Towers in Hilly Terrain to Typhoon Winds

Tapping Deep Water Resources
Lena is the first commercial guyed tower. Its jacket is the longest ever fabricated, loaded out and launched in one piece. Lena stands in 1,000 ft deep water and has a three-level oil...
