Lebensdauerbemessung im Betonbau

Service life design in concrete construction - From the deterioration process related to components to safety analysis of whole structures

Relevant methods for the lifetime management of concrete structures are the design for durability relating to new structures and the lifetime prediction relating to existing structures. These methods allow to manage the entire lifetime of a concrete structure while avoiding cost-intensive maintenance measures and corresponding downtimes. This paper focuses on the design for durability. Major emphasis is put on the presentation of methods to describe the behaviour of the concrete structure as a whole resulting from the integration of the deterioration effects on the member level. Based on the fact that different deterioration mechanisms occur in combination with each other, procedures for modelling interactions and singular risks (e. g. corrosion of tendons) are dealt with as well in this paper.
