Present and future probabilistic challenges for maintenance of reinforced concrete structures

In the coming decades the most developed countries face the task of maintaining their infrastructure. Probabilistic decision-making tools can support this challenge under the conditions of cost-effectiveness and safety requirements. Even though the fib MC2010 (2010) for concrete structures provides a basis for decision making, a probabilistic overall concept for dealing with existing structures is missing. In the framework of the development of fib MC2010 (2010), more emphasis is put on the assessment of existing structures and hence this paper idientifies challenges with respect to a probabilistic maintenance concept for existing concrete structures.
