The European pre-standard CEN/TS 1992-4 for the design of fastenings by means of headed studs, anchor channels as well as post-installed mechanical and chemical anchors is ready for use. The background and interpretation of the provisions related to the determination of actions and resistances based on limit state design, durability, fire resistance, fatigue and earthquake actions as required by CEN/TS 1992 are described in detail. Selected chapters from the German concrete yearbook are now being published in the new English "Beton-Kalender Series" for the benefit of an international audience. Since it was founded in 1906, the Ernst & Sohn "Beton-Kalender" has been supporting developments in reinforced and prestressed concrete. The aim was to publish a yearbook to reflect progress in "ferro-concrete" structures until - as the book's first editor, Fritz von Emperger (1862-1942), expressed it - the "tempestuous development" in this form of construction came to an end. However, the "Beton-Kalender" quickly became the chosen work of reference for civil and structural engineers, and apart from the years 1945-1950 has been published annually ever since.

Due to increasing traffic flows the extension of transport infrastructure with rail roads and high speed lines is an ongoing process worldwide. Ballastless track systems with concrete slabs are used more and more. Following the first trials in the 1970s and more than four decades of R&D work on ballastless track, the level of development is such that it can be confirmed that ballastless track is suitable for use as an alternative to ballasted track. This book makes a contribution to the state of the art of ballastless track by describing the basics for designing the ballastless track. Important advice is provided regarding the construction of ballastless track on earthworks and in tunnels. There is also a description of the technical history of the development of ballastless track on bridges and the ensuing findings for bridge design. The state of the art of ballastless track for switches, important information on details concerning drainage, transitions, accessibility for road vehicles and experience gleaned from maintenance round off the work.

The wind energy industry in Germany has an excellent global standing when it comes to the development and construction of wind turbines. Germany currently represents the world's largest market for wind energy. The ongoing development of ever more powerful wind turbines plus additional requirements for the design and construction of their offshore foundation structures exceeds the actual experiences gained so far in the various disciplines concerned. This book gives a comprehensive overview for planning and structural design analysis of reinforced concrete and pre-stressed concrete wind turbine towers for both, onshore and offshore wind turbines. Wind turbines represent structures subjected to highly dynamic loading patterns. Therefore, for the design of loadbearing structures, fatigue effects - and not just maximum loads - are extremely important, in particular in the connections and joints of concrete and hybrid structures. There multi-axial stress conditions occure which so far are not covered by the design codes. The specific actions, the nonlinear behaviour and modeling for the structural analysis are explained. Design and verification with a focus on fatigue are adressed. The chapter Manufacturing includes hybrid structures, segmental construction of pre-stressed concrete towers and offshore wind turbine foundations. Selected chapters from the German concrete yearbook are now being published in the new English "Beton-Kalender Series" for the benefit of an international audience.

The book introduces all the aspects needed for the safe and economic design and analysis of connections using bolted joints in steel structures. This is not treated according to any specific standard but making comparison among the different norms and methodologies used in the engineering practice, e.g. Eurocode, AISC, DIN, BS. Several examples are solved and illustrated in detail, giving the reader all the tools necessary to tackle also complex connection design problems. The book is introductory but also very helpful to advanced and specialist audiences because it covers a large variety of practice demands for connection design. Parts that are not taken to an advanced level are seismic design, welds, interaction with other materials (concrete, wood), and cold formed connections./p

Die Bemessung von Befestigungen mit Dübeln und Kopfbolzen in Beton wird in der Praxis häufig mit Computerprogrammen der Hersteller realisiert. Mit diesen Programmen sind die einfache Bemessung für unterschiedliche Randbedingungen, die Auswahl des optimalen Befestigungselementes und die Maximierung des Auslastungsgrades möglich. Der theoretische Hintergrund dieser Bemessungsverfahren ist komplex und basiert zum Teil auf bruchmechanischen Ansätzen. In diesem Buch werden die gebräuchlichen Bemessungsverfahren für Befestigungen in Beton (Dübel und Kopfbolzen) anschaulich erklärt und an zahlreichen Praxisbeispielen verdeutlicht, um den Anwendern von Bemessungsprogrammen und interessierten Lesern die Berechnungsgrundlagen zugänglich zu machen und die Berechnung beliebiger Anwendungsfälle zu ermöglichen.

Das Werk liefert eine einheitliche Darstellung der Baustatik auf der Grundlage der Technischen Mechanik. Es behandelt Stab- und Flächentragwerke nach der Elastizitäts- und Plastizitätstheorie. Es betont den geschichtlichen Hintergrund und den Bezug zur praktischen Ingenieurtätigkeit und dokumentiert erstmals in umfassender Weise die spezielle Schule, die sich in den letzten 50 Jahren an der ETH in Zürich herausgebildet hat. Als Lehrbuch enthält das Werk viele durchgearbeitete Beispiele und Aufgaben zum vertieften Studium. Die einzelnen Kapitel werden durch Zusammenfassungen abgeschlossen, welche die wichtigsten Lehrinhalte in prägnanter Form hervorheben. Die verwendeten Fachausdrücke sind in einem Anhang definiert. Als Nachschlagewerk enthält das Buch ein umfassendes Stichwortverzeichnis. Die Gliederung des Inhalts und Hervorhebungen im Text erleichtern die Übersicht. Bezeichnungen, Werkstoff- und Querschnittswerte sowie Abrisse der Matrizenalgebra, der Tensorrechnung und der Variationsrechnung sind in Anhängen zusammengefasst. Insgesamt richtet sich das Buch als Grundlagenwerk an Studierende und Lehrende ebenso wie an Bauingenieure in der Praxis. Es bezweckt, seine Leser zu einer sinnvollen Modellierung und Behandlung von Tragwerken zu befähigen und sie bei den unter ihrer Verantwortung vorgenommenen Projektierungs-und Überprüfungsarbeiten von Tragwerken zu unterstützen. Die 1. Auflage war erfreulicherweise nach kurzer Zeit vergriffen, so dass diese 2., korrigierte Auflage vorgelegt werden kann.
