The benchmark case-study, available in literature, is characterized by a 1-bay 1-storey frame, subjected to cyclic tests, accounting for two configurations: (a) infilled with traditional masonry; (b) bare frame. The obtained numerical results were compared with the experimental ones, showing a near-perfect agreement for the benchmark and providing a numerical base for future investigations.

To improve the behaviour of infill RC frames under seismic actions, new approaches could be exploited, considering that construction companies prefer dry construction techniques, due to an evident reduction of weight, a consistent lower construction time and a greater sustainability. This study presents some preliminary numerical analysis to reproduce the results of an experimental campaign characterized by the investigation of different infill technologies. The focus of the study is the performance evaluation of cross laminated timber (CLT) infill panels in RC frames, in comparison with the response provided by traditional masonry infill panel.
