In this paper, numerical investigations have been carried out on masonry infilled steel frames with rigid or semi-rigid beam-to-column connections. A simple and reliable model based on a lumped plasticity approach is adopted for the structural steel members as well as for the masonry infills, with the in-plane non-linear behavior being simulated by a single (equivalent) diagonal strut element. After a preliminary validation of the model on beam-column joint subassemblies and on a one-storey masonry infilled frame, the response of multi-storey 2D masonry-infilled steel frames are investigated through push-over and non-linear time-history analyses. The results of a series of parametric analyses are presented, by varying not only the mechanical properties of the beam-column connections but also the geometric configuration of the frames and the spatial distribution of the infills. The numerical validation of the model onto experimental results available in literature confirms the reliability of the model presented. The parametric analyses performed on the multi-storey frames provide preliminary useful indications for an accurate seismic design.
