项目摘要

Before concrete is hardening it is plastic to liquid and can preserve almost any shape in the setting process. The possibility of free shaping when using reinforced concrete for construction is thus given. However, today the design language of ordinary reinforced concrete structures is very easy, especially for cost reasons. Plane surfaces and rectangular geometry are the rule. We have two main objectives: (1) The goal is an aesthetic change of paradigm, because the expansion of the spectrum of the usual forms of concrete increases the possibilities of design in building with concrete. The buildings should be functional, while allowing variable uses. (2) Lightweight building with concrete accordingly "form follows force" leads to a reduction in the dead weight of the components, saving of natural resources and energy in fabrication the building materials but also to a reduction in CO2 emissions. Our aim is that relevant structural elements such as ceilings, walls, columns get their geometry according to the principle "form follows force" as a result of the given, but also influenceable force flow in the component. We want to find the constructive and theoretical basics for design, calculation and construction of free-form and lightweight designed concrete components. Special focus will be the component-specific basic research. The whole buildable structures - shells, plates, columns - should be explored. The components, which are designed according to force fields are, ideally, minimum weight. Indications for effective bearing structures are offered by nature with the help of bionics. Another focus is the development of formwork systems and building technologies for free-formed concrete structures. Joining technologies are in terms of deconstruction and reuse of (parts) of concrete structures of interest. In addition, appropriate calculation methods must be developed to design stability endangered structures safely. The main objective of applied mathematical research - specifically of differential geometry - is to make the design language for the lightweight concrete describable and to analyse the force distributions and to define them mathematically.

在混凝土硬化之前，它是塑性的，可以在凝固过程中保持几乎任何形状。从而为钢筋混凝土施工提供了自由成型的可能性。然而，今天普通钢筋混凝土结构的设计语言非常容易，特别是出于成本原因。平面和矩形几何是规则。我们有两个主要目标：（1）我们的目标是美学范式的改变，因为混凝土常用形式的范围的扩大增加了混凝土建筑设计的可能性。建筑物应该是功能性的，同时允许各种用途。(2)因此，混凝土轻质建筑“形式遵循力量”，减少了构件的自重，节省了自然资源和制造建筑材料的能源，还减少了二氧化碳排放。我们的目标是，相关的结构元素，如天花板，墙壁，柱子，根据“形式遵循力”的原则，通过给定的，但也是组件中的影响力流来获得它们的几何形状。我们希望为自由形式和轻质设计的混凝土构件的设计，计算和施工找到建设性和理论基础。特别重点将是特定组件的基础研究。应该探索整个可建造的结构--壳、板、柱。根据力场设计的部件在理想情况下重量最小。在仿生学的帮助下，自然界提供了有效承载结构的指示。另一个重点是自由成型混凝土结构的模板系统和建筑技术的发展。连接技术是对感兴趣的具体结构（部分）的解构和重用。此外，必须开发适当的计算方法来安全地设计稳定性受到威胁的结构。应用数学研究的主要目标--特别是微分几何--是使轻质混凝土的设计语言可描述，分析力的分布，并在数学上定义它们。
