Masonry infills are critical components of reinforced concrete (RC) frame structures that often sustain significant damage, even during moderate earthquakes. Rubber joints have emerged as a promising solution to enhance their performance. However, further experimental and numerical investigations are required to assess their effectiveness under realistic seismic loading conditions. To address this gap, the H2020 EU-funded FLEJOI project (FLExible JOInts for seismic-resilient design of masonry-infilled RC frames) was conducted within the ERIES framework. As part of this initiative, two identical RC brick-infilled prototypes were constructed at the Dynamic Testing Laboratory of IZIIS in North Macedonia, each incorporating a distinct rubber joint system. One system was designed to reduce the infill stiffness while introducing damping capabilities, whereas the other aimed to fully decouple the infills from the frame. The prototypes underwent a series of shaking table tests to evaluate their seismic performance. A comprehensive set of sensors was installed to monitor key parameters influencing the seismic response of the structures, infills, and joints. This paper presents an overview of the experimental testing campaign and the data generated. These data will support the calibration and validation of numerical models and serve as a foundation for further studies on the seismic performance of RC frames with masonry infills and rubber joint systems.
