Migrating to Eurocode 3 is the main topic of the 2011 Steel Structures Yearbook which focusses on joints and connections.
Stahlbau-Kalender 2010. Schwerpunkt: Verbundbau
Fur die neue Ausgabe des Stahlbau-Kalenders wurde ein Schwerpunkt gesetzt, der in der Planungspraxis zunehmend eine Rolle spielt. Die Verbundbauweise bietet innovative Tragwerkslosungen fur den Hoch- und Industriebau. Die erfolgreiche Verbreitung im Hochhaus- und Geschossbau in den letzten 20 Jahren ist den zahlreichen Vorteilen dieser Bauweise geschuldet: Wirtschaftlichkeit durch kurze Montagezeiten mit fortschrittlicher Anschlusstechnik, mehr Gestaltungs"freiraum" mit gro?en Spannweiten und geringen Bauhohen. Gegenuber dem reinen Stahlbau ermoglicht der Verbund von Stahl und Beton intelligente ganzheitliche Losungen durch integrierten Brandschutz. Fur den jungeren Gebaudebestand mit Stahl-Glas-Fassaden ergeben sich vor dem Hintergrund der Energieeinsparverordnung (EnEV) Fragen und nicht selten die Notwendigkeit von energetischen Sanierungsma?nahmen. Zukunftig Sanierungsfalle vermeiden und den Bestand untersuchen hilft die neue DASt-Richtlinie 022 «Feuerverzinken von tragenden Stahlbauteilen», deren Hintergrunde ausfuhrlich erlautert werden.
Bauphysik-Kalender 2012. Schwerpunkt - Gebäudediagnostik
Die Gebäudediagnostik hat sich zum Schlüsselthema der Bauphysik entwickelt – und zwar sowohl für die Bestandsaufnahme und -bewertung als auch für die Inbetriebnahme und das Einfahren von Neubauten und deren planmäßiges langfristiges Monitoring zur Überwachung der Funktionsfähigkeit. Die gewachsenen technischen Möglichkeiten der Gebäudediagnostik mit einer Vielzahl von Mess- und Prüftechniken ermöglichen eine komplexe, ganzheitliche Analyse und Planung und sind somit wesentliche Grundlage für nachhaltiges Bauen. Im neuen Bauphysik-Kalender 2012 mit dem Schwerpunktthema «Gebäudediagnostik» werden zerstörende und zerstörungsfreie Prüfverfahren zur Bestimmung von Materialeigenschaften und ihre Anwendung auf alle Bauarten zur Tragwerksdiagnose und Bestimmung der Tragsicherheit praxisgerecht erläutert. Weiterhin werden die Mess- und Analysemethoden zur Untersuchung der Gebrauchseigenschaften und des energetischen Verhaltens (Performance) von Gebäuden, wie z. B. Raumluftqualität, Wärmegewinne und -verluste und Schadstoffemission, aufgeführt. Die praxisgerechten Erläuterungen schließen Beispiele verschiedenster Gebäudetypen bis hin zur Dauerüberwachung denkmalgeschützter Bauwerke ein. Auf aktuellem Stand sind wie immer die Materialtechnischen Tabellen.

Using the Weibull Distribution. Reliability, Modeling, and Inference
Understand and utilize the latest developments in Weibull inferential methods While the Weibull distribution is widely used in science and engineering, most engineers do not have the necessary statistical training to implement the methodology effectively. Using the Weibull Distribution: Reliability, Modeling, and Inference fills a gap in the current literature on the topic, introducing a self-contained presentation of the probabilistic basis for the methodology while providing powerful techniques for extracting information from data. The author explains the use of the Weibull distribution and its statistical and probabilistic basis, providing a wealth of material that is not available in the current literature. The book begins by outlining the fundamental probability and statistical concepts that serve as a foundation for subsequent topics of coverage, including: • Optimum burn-in, age and block replacement, warranties and renewal theory • Exact inference in Weibull regression • Goodness of fit testing and distinguishing the Weibull from the lognormal • Inference for the Three Parameter Weibull Throughout the book, a wealth of real-world examples showcases the discussed topics and each chapter concludes with a set of exercises, allowing readers to test their understanding of the presented material. In addition, a related website features the author's own software for implementing the discussed analyses along with a set of modules written in Mathcad®, and additional graphical interface software for performing simulations. With its numerous hands-on examples, exercises, and software applications, Using the Weibull Distribution is an excellent book for courses on quality control and reliability engineering at the upper-undergraduate and graduate levels. The book also serves as a valuable reference for engineers, scientists, and business analysts who gather and interpret data that follows the Weibull distribution
