During the last decades completely new technologies for high speed railway vehicles have been developed. The primary goals have been to increase traction, axle load, and travelling speed, and to guarantee the safety of the passengers. However, new developments have revealed new limitations: settlement and destruction of the ballast and the subgrade lead to deterioration of the track; irregular wear of the wheels causes an increase in overall load and deterioration in passenger comfort; and damage of the running surfaces of the rail and the wheel is becoming more frequent. These problems have been investigated in the Priority Programme SPP 1015 supported by the Deutsche Forschungsgemeinschaft (DFG), with the goal of better understanding of the dynamic interaction of vehicle and track, and the long-term behavior of the components of the system. The book contains the scientific results of the programme as presented at the concluding colloquium held at University of Stuttgart, Germany, 2002.
Zehn Jahre nach der 1. Auflage in englischer Sprache legt der Autor sein Buch The History of the Theory of Structures in wesentlich erweiterter Form vor, nunmehr mit dem Untertitel Searching for Equilibrium. Mit dem vorliegenden Buch lädt der Verfasser seine Leser zur Suche nach dem Gleichgewicht von Tragwerken auf Zeitreisen ein. Die Zeitreisen setzen mit der Entstehung der Statik und Festigkeitslehre eines Leonardo und Galilei ein und erreichen ihren ersten Höhepunkt mit den baustatischen Theorien über den Balken, Erddruck und das Gewölbe von Coulomb am Ende des 18. Jahrhunderts. Im folgenden Jahrhundert formiert sich die Baustatik mit Navier, Culmann, Maxwell, Rankine, Mohr, Castiglia...
Between 1355 and 1806 the title of Poet Laureate was bestowed on around 1500 persons in the territories of the Holy Roman Empire. In some cases the title was conferred by the Emperor himself, on his own initiative or in response to a petitioner. In others the title was granted by a count palatine acting upon the Emperor's behalf, but an even larger number had the title bestowed on them by various German universities exercising this privilege under the Emperor's authority. The lives and publications of 1340 of these poets were detailed in the four-volume Poets Laureate in the Holy Roman Empire: A Bio-bibliographical Handbook published in 2006. This supplementary volume provides similar information about some 130 further poets who have come to light since that work was published. Furthermore, it updates, augments and - where necessary - corrects details relating to the poets covered in the previous volumes. In particular, it includes extensive new information about the two dozen women poets who were laureated in the seventeenth and eighteenth centuries. Poets Laureate in the Holy Roman Empire: A Bio-bibliographical Handbook, Volume 1–4 is still available for purchase.
Includes entries for maps and atlases.
First published in 1995. CRC Press is an imprint of Taylor & Francis.
The proceedings contain contributions presented by authors from more than 30 countries at EURODYN 2002. The proceedings show recent scientific developments as well as practical applications, they cover the fields of theory of vibrations, nonlinear vibrations, stochastic dynamics, vibrations of structured elements, wave propagation and structure-borne sound, including questions of fatigue and damping. Emphasis is laid on vibrations of bridges, buildings, railway structures as well as on the fields of wind and earthquake engineering, repectively. Enriched by a number of keynote lectures and organized sessions the two volumes of the proceedings present an overview of the state of the art of the whole field of structural dynamics and the tendencies ot its further development.

Was wissen Bauingenieure heute über die Herkunft der Baustatik? Wann und welcherart setzte das statische Rechnen im Entwurfsprozess ein? Wir ahnen wohl, dass die Entwicklung von Berechnungsmethoden und -verfahren im engen Zusammenhang mit der Entdeckung neuer Baumaterialien und der Hervorbringung und Entfaltung von Tragformen stehen. Das vorliegende Buch zeichnet die Entstehung von Statik und Festigkeitslehre als die Entwicklung vom geometrischen Denken der Renaissance über die klassische Mechanik bis hin zur modernen Strukturmechanik nach. Eine Einführung eröffnet mit kurzen Einblicken in zwölf verbreitete Berechnungsverfahren den Zugang zu über 500 Jahren Geschichte der Baustatik aus...
