Book Description
This handbook offers all aspects of Overhead Transmission Lines as the backbone of networks of electrical power. The content of the book includes, after a historical flash-back: Planning and management concepts, electrical and mechanical considerations, influences of the weather, and on the environment, detailed design of all line components, construction and maintenance aspects, line optimization, and asset management, as well as a comparison between overhead lines and underground cables. The book was written by more than 50 experts and assembled through the Cigré study committee on Overhead Lines. This guarantees valuable exchange and dissemination of unbiased information for technical but also non-technical audiences.

Book Description
Timber's strength, light weight, and energy-absorbing properties furnish features desirable for bridge construction. Timber is capable of supporting short-term overloads without adverse effects. Contrary to popular belief, large wood members provide good fire resistance qualities that meet or exceed those of other materials in severe fire exposures. From an economic standpoint, wood is competitive with other materials on a first-cost basis and shows advantages when life cycle costs are compared. Timber bridges can be constructed in virtually any weather conditions, without detriment to the material. Wood is not damaged by continuous freezing and thawing and resists harmful effects of de-icing agents, which cause deterioration in other bridge materials. Timber bridges do not require special equipment for installation and can normally be constructed without highly skilled labor. They also present a natural and aesthetically pleasing appearance, particularly in natural surroundings. The misconception that wood provides a short service life has plagued timber as a construction material. Although wood is susceptible to decay or insect attack under specific conditions, it is inherently a very durable material when protected from moisture. Many covered bridges built during the 19th century have lasted over 100 years because they were protected from direct exposure to the elements. In modem applications, it is seldom practical or economical to cover bridges; however, the use of wood preservatives has extended the life of wood used in exposed bridge applications. Using modem application techniques and preservative chemicals, wood can now be effectively protected from deterioration for periods of 50 years or longer. In addition, wood treated with preservatives requires little maintenance and no painting. Another misconception about wood as a bridge material is that its use is limited to minor structures of no appreciable size. This belief is probably based on the fact that trees for commercial timber are limited in size and are normally harvested before they reach maximum size. Although tree diameter limits the size of sawn lumber, the advent of glued-laminated timber (glulam) some 40 years ago provided designers with several compensating alternatives. Glulam, which is the most widely used modem timber bridge material, is manufactured by bonding sawn lumber laminations together with waterproof structural adhesives. Thus, glulam members are virtually unlimited in depth, width, and length and can be manufactured in a wide range of shapes. Glulam provides higher design strengths than sawn lumber and provides better utilization of the available timber resource by permitting the manufacture of large wood structural elements from smaller lumber sizes. Technological advances in laminating over the past four decades have further increased the suitability and performance of wood for modern highway bridge applications.

Book Description
Until now, information on the dynamic loading of structures has been widely scattered. No other book has examined the different types of loading in a comprehensive and systematic manner, and looked at their signficance in the design process. The book begins with a survey of the probabilistic background to all forms of loads, which is particularly important to dynamic loads, and then looks at the main types in turn: wind, earthquake, wave, blast and impact loading. The relevant code provisions (Eurocode and UBC American) are detailed and a number of examples are used to illustrate the principles. A final section covers the analysis for dynamic loading, drawing out the concepts underlying the treatment of all dynamic loads, and the corresponding modelling techniques. Throughout there is a focus on the modelling of structures, rather than on classical structural dynamics.

Book Description
Dieses Buch führt in alle Aspekte der sicheren Berechnung, Bemessung und Konstruktion von wirtschaftlichen modernen Verbindungen im Stahlbau ein. Die Hintergrunderläuterungen sind nicht an eine spezifische Norm gekoppelt, sondern es werden unterschiedliche Normen und Methoden verglichen, die in der Praxis zur Anwendung kommen, wie z. B. Eurocode, AISC, DIN, BS. Anhand einer Reihe von Beispielen werden Problemlösungen detailliert beschrieben und illustriert. Damit erhält der Leser alle notwendigen Werkzeuge an die Hand, um auch komplexe Probleme bei der Konstruktion von Verbindungen zu lösen. Das Buch ist für Berufseinsteiger, für erfahrene Praktiker sowie auch für Stahlbaufachleute eine Arbeitshilfe, denn es werden einfache und komplexe Beanspruchungen an Verbindungen abgebildet. Weniger ausführlich werden Erdbebenauslegung, Schweißnähte, die Wechselwirkung mit anderen Materialien (Beton, Holz) und kalt geformte Verbindungen behandelt.

Book Description
This Standard provides a uniform basis for the design, detailing, fabrication, testing, assembly, and erection of steel tubular structures for electrical transmission poles. These guidelines apply to cold-formed single- and multipole tubular steel structures that support overhead transmission lines. The design parameters are applicable to guyed and self-supporting structures using a variety of foundations, including concrete caissons, steel piling, and direct embedment. Standard ASCE/SEI 48-11 replaces the previous edition (ASCE/SEI 48-05) and revises some formulas that are based on other current industry standards. This Standard includes a detailed commentary and appendixes with explanatory and supplementary information. This Standard will be a primary reference for structural engineers and construction managers involved in designing and building electrical transmission lines, as well as engineers and others involved in the electric power transmission industry.
