On a generic framework for systems resilience modelling of bridges - accounting for historic and cultural values

Resilient and sustainable traffic infrastructure systems such as bridges play a crucial role in societal economic growth. During the last decades, substantial research has been undertaken for the optimal management of risks associated with extreme events, and the concept of resilience was introduced. The knowledge on the system characteristics affecting resilience is increasing and so is the capability to model and analyze systems. The first step in systems modelling and analysis is to define the system which has not been addressed methodically in the literature. In this contribution, we provide a framework for systems identification in the context of resilience informed management of historic bridges. The proposed approach rests on the indicator-based systems modelling framework of the Joint Committee on Structural Safety (JCSS). With this basis we identify ten resilience indicators which provide information concerning the resilience performances of historic bridges. Finally, we apply the suggested approach through an example.
