Deflections and temperature are given and compared with traditional engineering models and advises for future problems are presented. For bridge girders with I cross sections, welded thick plates are used and there joining need to be considered precisely. Effect from welding, such as deflections and residual stresses, will have an outcome on the performed component. For welding of thick plates multi-layer welding is used. The edges need to be cut before welding. The preparation process needs to be considered as well as actual joining to have an economic performance. As joint geometry the Z-joint was chosen and investigated. Results from testing as well as from the welding simulation will be shown and compared.

Ein F{\"u}gen dieser Module auf der Baustelle zu einer Gesamtstruktur ist aber weiterhin notwendig. Als F{\"u}geverfahren wird hier h{\"a}ufig das MAG-Mehrlagenschweißen eingesetzt. Gerade an dicken Blechen stellen Baustellenschweißungen nicht nur besondere Anforderungen an den ausf{\"u}hrenden Betrieb, die Bauleitung und Bau{\"u}berwachung, sondern auch an den Konstrukteur. Wichtig f{\"u}r den Konstrukteur ist die Kenntnis der sich durch Schweißungen einstellenden Schrumpfung der Bauteile, der auftretenden Verz{\"u}ge und Eigenspannungen. Gerade bei Baustellenschweißungen m{\"u}ssen diese Aspekte in der Konstruktionsphase der Einzelkomponenten mit ber{\"u}cksichtigt werden, um die erforderlichen Toleranzen bei der Montage einzuhalten. Eine genaue Kenntnis der durch Schweißungen verursachten Ph{\"a}nomene ist in den Konstruktions- und Montagebetrieben oft nur aus mehrj{\"a}hrigen Erfahrungen vorhanden. Ein grundlegendes, vollst{\"a}ndiges Bild der Abl{\"a}ufe beim Schweißen auf der Baustelle, das es erm{\"o}glicht, dieses Wissen auf neue Konstruktionen zu {\"u}bertragen, fehlt bisher. Insbesondere f{\"u}r die immer {\"o}fter im Br{\"u}cken- und Stahlhochbau eingesetzten h{\"o}herfesten Feinkornbaust{\"a}hle (z.B. S460) ist die Kenntnis des Verhaltens bei Baustellenschweißungen notwendig. Hier setzt der Forschungsantrag an. Mit Hilfe der Schweißsimulation k{\"o}nnen die Auswirkungen von Schweißn{\"a}hten, wie die Entstehung von Verz{\"u}gen und Eigenspannungen am Bauteil, global dargestellt werden. Eine anschließende Struktursimulationen (Festigkeits- und Steifigkeitsberechnungen) mit aus der Schweißsimulation integrierten Ergebnissen bildet die Basis f{\"u}r erg{\"a}nzende Untersuchungen. Montagest{\"o}ße sind außerdem durch Verschmutzung und Witterung negativ beeinflusst. Die Montage kann beispielsweise bei niedrigen Temperaturen unterhalb des Gefrierpunkts durchgef{\"u}hrt werden m{\"u}ssen. Diese Situation wurde in einer Klimakammer simuliert und die Auswirkungen der Umgebungstemperatur bei der Montage auf das Tragverhalten der Verbindung untersucht. F{\"u}r die im Rahmen des Vorhabens untersuchten F{\"a}lle ist kein Einfluss variierender Umgebungstemperaturen bis -10 °C auf die resultierenden Schweißeigenspannungen festzustellen. Der Vergleich von Verzug und Eigenspannung gegen{\"u}ber normativ vorgegeben Toleranzwerten sowie vereinfachten Ingenieurmodellen f{\"u}r die Approximation des Eigenspannungsverlaufs zeigt große Defizite.
