A novel energy-dissipating hysteretic infilled wall system comprising slotted concrete blocks with energy-dissipating links is designed and experimentally tested in a full-scale reinforced concrete frame. Its performance is compared with the conventional (brick) infilled frame as well as bare frame. This infill wall system helps to reduce the stiffening effect and also acts as a secondary load-resisting system that resists lateral loads even after the formation of plastic hinges in the frame. The post-yield response of the frame becomes stable and no collapse condition arises even at a large deformation. This is a kind of low-cost passive energy–dissipating method that may act as an efficient and versatile solution to minimize the damages in frame buildings. A systematic numerical model is developed on the basis of a series of experiments conducted on its constituent units that captures the elastic and post-yield load deformation behavior of the energy-dissipating hysteretic infilled frame under cyclic loading.
