The aim of the subproject is the development of a new methodology for characterising the load-bearing mechanisms (compression softening, aggregate interlocking, mixed-mode fracture as well as dowel action of carbon reinforcement) activated in carbon reinforced concrete membranes. Based on this, material-specific compression field models will be developed which allow a realistic assessment of structural behaviour and deformation capacity of membranes with non-metallic reinforcements under plane stresses. These models constitute the theoretical basis for implementation of material-minimised membrane structures made of carbon reinforced concrete.

该子项目的目的是开发一种新的方法，用于表征碳增强混凝土膜中激活的承载机制（压缩软化、骨料互锁、混合模式断裂以及碳增强的销钉作用）。在此基础上，将开发特定材料的压缩场模型，允许现实的评估与非金属加固膜的结构行为和变形能力在平面应力下。这些模型构成的理论基础，实施材料最少的碳钢筋混凝土膜结构。
