In order to reduce the damage degree of masonry infills and improve their deformation recoverability under earthquake, based on the failure mechanism of infill walls of reinforced concrete frames, a structural measure of installing horizontal slip layers (HSLs) in masonry infills constructed by hollow bricks is put forward. Two groups of full-scale HSL-specimens were manufactured and tested under quasi-static loads to study the seismic behaviors of HSL-frame structures. A calculation method for measuring the damage degree of infills is proposed and their damage degree after adding HSLs are compared. Results show that after HSLs are added in the hollow brick infills, the diagonal bracing effect of the infill walls is weakened. With the HSLs, the failure mode of the infill walls changes from diagonal failure to sliding failure, the energy dissipation capacity of frames increases, and the damage degree of the infills and their residual deformation are decreased significantly. In our experiment, the residual deformation decreased by 27% and the failure ratio decreased by more than 93%.
