Title:
Abstract:	Die Anwendung von trapezförmig gekanteten Stegen im Verbundbrückenbau bietet zahlreiche Vorteile. Durch die Einbindung des gekanteten Stahlstegs in den Betongurt ist die direkte Übertragung von Schubkräften und Biegemomenten in der Verbundfuge möglich. Die zusätzliche Anordnung von randnahen Kopfbolzen steigert die Tragfähigkeit und verbessert die Gebrauchstauglichkeit der Verbundfuge. Da die Kopfbolzen nahe zum Bauteilrand des Stahlbetongurts angeordnet werden, muss der Einfluss dieser randnahen Ausbildung, insbesondere die hervorgerufenen Spaltzugkräfte, berücksichtigt werden. Dieser Beitrag stellt Forschungsergebnisse von experimentellen und numerischen Untersuchungen zu einer Längsschub- und einer Querbiegebeanspruchung der Verbundfuge dar. Es wird das Tragverhalten der Verbindung erläutert. Außerdem werden Bemessungsgleichungen für diese Beanspruchungen bereitgestellt sowie konstruktive Hinweise gegeben. Corrugated steel webs in composite construction - longitudinal shear and transverse bending moment with headed studs close to the concrete surface. The application of corrugated steel webs in composite bridges leads to many advantages. The embedment of the corrugated web allows transferring shear forces and bending moments at the composite connection. The additional arrangement of horizontally lying headed studs increases the carrying capacity and improves the serviceability of the composite connection. As the headed studs are positioned close to the surface of the concrete slab, the edge influence inducing splitting forces has to be considered. This paper shows results of research work on longitudinal shear and transverse bending moment at the composite connection. The load carrying behavior is illustrated. Furthermore design equations of the resistances and some constructional recommendations are given.
