Long-term damage processes in RC-folded plate structures with textile reinforcement B. Moller, W. Graf, A. Hoffmann & F. Steinigen Dresden University of Technology, Department of Civil Engineering D-01062 Dresden, Mommsenstr. 13, Germany Abstract Temporal and spatial progressive damage processes in reinforced concrete folded plate structures with additional textile reinforcement are described by means of a multi-reference-plane model (MRM). The global damage state is described using a dynamic damage indicator. By considering the example of a spatial reinforced concrete floor construction with textile post-reinforcement, the change in the damage indicator during its service life is demonstrated. Introduction The aim of structural planning is to realize economic, safe and durable constructions. In the standard procedure for analyzing reinforced concrete constructions - semi-probabilistic safety concept (e.g. Eurocode 2) - only the initial state of the supporting structure is con
