Abstract:	Für den der Nachweis Standsicherheit von Flachbodentanks müssen Statiker und Hersteller insbesondere kombinierte Lasteinwirkungen zuverlässig ermitteln. Dazu zählen unter anderem Wind- oder Schneelasten genauso wie Verkehrslasten auf den Dächern oder Drücke und Sogwirkungen. Das Tragverhalten von Flachbodentanks ist aufgrund ihrer Konstruktion komplex. Die verschiedenen Einwirkungen werden zunächst individuell und dann in Kombination bestimmt, um wiederum ihre Auswirkungen auf das Bauwerk zu ermitteln. Die Herausforderung: Bautechnische Standsicherheitsnachweise sind mit Einführung des Eurocodes teilweise aufwändiger. Außerdem weichen dessen Regeln, um die Kombination von Lasten zu bestimmen, von jenen der DIN 18800 ab. Während der erste Teil dieses Beitrags [1] eine einheitliche Anwendung und ein praxisgerechtes, allgemein abgestimmtes Vorgehen diskutiert hat, stehen im zweiten Teil die Beispiele im Vordergrund. Load combinations for flat-bottom storage tanks according to Eurocodes - Examples (part 2). Structural engineers and manufacturers must produce reliable calculations, particularly of load combinations, to establish the structural integrity of flat-bottom storage tanks. Load types include for example wind or snow and live loads on tank roofs as well as pressure and suction. Given by the design and construction of flat-bottom tanks, their load-bearing characteristics are complex. The various load types must be determined, first individually and then in combination, before their impact on the structure can be calculated. The challenging nature of the task is exacerbated by the increased complexity of structural stability analyses that has accompanied the introduction of the Eurocode. In addition, the rules specified in the Code for the calculation of load combinations deviate from those in the DIN 18800 standard. The first part of the article [1] examined possibilities for uniform application and a practical procedure in line with general consensus, while the second section focuses on examples.
