Design of Liquid Retaining Structures – Remarks on the Rules of the Guideline “Watertight Concrete” The use of watertight concrete structures is regulated by the guideline “Watertight Concrete” of the German Committee of Reinforced Concrete, especially requirements on the serviceability limit states. The scope of the guideline is valid for liquid retaining structures too. The essential characteristic of those structures is their defined tightness. Design concepts in order to fullfill requirements on durability of concrete tanks are discussed. Moreover, recommendations due to the design of moderate prestressed reinforced concrete tanks are given, containing the durable filling of planned cracks. Design aspects of the European Standard EC 2 Part 3 are discussed too. 相似文献

Light‐Weight Structures made of thin walled, dry jointed surface elements made of UHPFRC With the development of novel jointed, thin walled and thus light components the resource‐efficient use of ultra‐high performance fiber‐reinforced fine grained concrete in structures can be realized. The manufacturing of modular and efficient UHPFRC components is achieved by the digital workflow as a result of digital design, calculation and CNC‐controlled manufacturing technology. By linking lightweight concrete components with new, high‐precision non standardized joints, such components can be connected material and force flow compatible with each other. The results with dry jointed T‐beams show the manufacturability and the potential of the dry jointing system on a large scale. When checking the load capacity of thin‐walled construction elements, the influence of fiber reinforcement must be especially considered. 相似文献
