The subproject develops a simulation method for the structural analysis of shells made of carbon reinforced concrete. The focus lies on the numerical homogenization of their interior structure. The method allows the analysis of large structures with detailed insight into the interior of the material. The special feature is that the stress-resultants required for the shell theory are determined by means of a representative volume element for the underlying shell kinematics, which is to be developed. Image-based methods are used for a realistic representation of the interior structure. The resulting geometry is described with a novel Scaled-Boundary Finite Element Method.

子项目开发了一种碳增强混凝土壳结构分析的模拟方法。重点在于其内部结构的数值均质化。该方法允许对大型结构进行分析，并详细了解材料的内部。其特殊之处在于，壳理论所需的应力结果是通过一个具有代表性的壳运动体单元来确定的，这是有待开发的。基于图像的方法用于内部结构的逼真表示。所得到的几何形状用一种新颖的尺度边界有限元方法来描述。
