| Abstract: | In addressing the challenge of ageing infrastructure, continuous structural monitoring has figured prominently in the development of tools for risk management and life-cycle prognostic strategies. However, a primary challenge lies in robustly quantifying structural condition using, typically indirect, monitoring observations. In recent years, a vast number of various data-driven or hybrid analysis methods have been proposed, targeting different levels of the so-called Rytter's hierarchy of damage identification. The more advanced identification tasks, relating to a more precise characterization (e.g., location and quantity) of damage are nontrivial to address. A primary difficulty in this respect relates to lack of labelled data corresponding to predefined damage states of the structure of interest. This implies that for most practical contexts, such structural identification ought to be achieved in an unsupervised manner. This work presents a new full-scale bridge experimental benchmark which can serve as a case study for verification and validation of damage identification schemes. The Ponte Moesa Campagnola (PMC) benchmark structure, which was decommissioned in 2019, represents a typical bridge structure of the Swiss Roadway Network. The bridge was subjected to a 4-day monitoring campaign, during which controlled damage progression scenarios were implemented. The monitored quantities comprised a multimodal mix of both acceleration and strain information, continually recorded during the 4-day campaign. The reported results demonstrate the potential of this data set to serve for structural identification and damage detection (DD) purposes. To this end, we present—merely as a viability study—the successful implementation of three damage-sensitive features (DSFs). The goal was to describe the data set and introduce it for further study, testing, and validation of emerging DD algorithms tailored for full-scale structural health monitoring (SHM) utilization.
