Title:
Abstract:	Holz-Beton-Verbundkonstruktionen weisen als hybride Tragwerke gegenüber reinen Holz- bzw. Stahlbetonkonstruktionen zahlreiche Vorteile auf. Wesentlich für die Effizienz der Hybridbauweise ist die Ausbildung der Verbundfuge. Der vorliegende Beitrag stellt ein neues Verbundelement für Straßenbrücken in Holz-Beton-Verbundbauweise vor, welches im Rahmen eines Forschungsprojekts an der Bauhaus-Universität Weimar entwickelt wurde. Die rechnerische Analyse der Verbundkonstruktion erfolgt - abweichend von den im Hybridbau bisher üblichen Berechnungsmethoden - unter Anwendung von Energiemethoden und Nutzung von Algorithmen der mathematischen Optimierung. Calculation of timber-concrete composite structures using mathematical optimization methods. Timber-concrete composite structures have many advantages over conventional timber and re inforced concrete structures. The efficiency of such hybrid structures significantly depends on the properties of the com posite joint. This article presents a novel structural element for the joint of timber-concrete composite bridges, which was developed as part of a research project at the Bauhaus-Universität Weimar. In contrast to standard calculation methods, an energy method and the mathematical optimization is applied for the numerical analysis of the hybrid structure.
