FEM SIMULATION OF THE IN-PLANE SEISMIC EXPERIMENTAL RESPONSE OF R.C. FRAMES WITH UNREINFORCED AND BED-JOINT REINFORCED AAC MASONRY INFILLS

Unreinforced masonry infills in RC structures are used worldwide and commonly built in complete adherence with the RC frame without any reinforcement and/or fastening. Accord-ing to post-seismic surveys and experimental studies, due to the intrinsic vulnerability of these non-structural elements, they can cause considerable economic and downtime losses, and even threat human lives. Although several researchers have studied the seismic behaviour of masonry infills, the response of AAC masonry and the solution with the bed-joint reinforce-ment need further studies starting from the available experimental results. The present paper introduces preliminary results of a numerical research where in-plane experimental tests car-ried out on unreinforced and bed-joint reinforced AAC masonry infills have been simulated through nonlinear FEM analysis. The numerical simulation has been anticipated by a cali-bration of the materials according to tests of characterization. Moreover, the influence of the bed-joint reinforcement on the in-plane seismic behaviour has been numerically studied, and the results have been compared to the unreinforced solution.
