Special issue design of electric transmission lines

EDITORIAL Special issue Design of electric transmission lines This special issue of Engineering Structures is devoted entirely to the structural and geometric design of overhead electric transmission lines. It includes a broad spectrum of papers from an international group of experts and innovators. The operating environment for transmission line engineers and planners is changing rapidly. Privatization and deregulation have created new pressures to cut down costs. At the same time, environmental and right-of-way constraints have become much more stringent. As a result, the power industry is being challenged to increase its productivity, take advantage of new computer technologies, question its practices and look for innovative solutions. The subjects covered in the papers of this special issue should all be of great interest to the practicing transmission line engineer facing these new challenges. Engineering Structures has specialized in bringing papers dealing with structures which are primarily controlled by natural forces, such as wind and earthquake, to the profession. The structures described in this collection of papers may be subjected to such forces, as well as to ice and extreme temperature fluctuations, and involve the application of state-of-the-art technology in analysis and proportioning. We are grateful to Professor Alain H. Peyrot of the University of Wisconsin, Madison, USA and Professor S. Kitipornchai of the University of Queensland, Australia for their efforts in assembling these papers which were contributed by experienced and respected researchers and practitioners from several countries.
