Sažetak
This paper gives an overview of the experimental results obtained by testing three reinforced concrete (RC) frame models with strong infill walls and one bare RC frame model for comparison. The experimental results of the RC frame models with and without a strong masonry infill are presented in terms of the collapse mechanism, lateral resistance, lateral stiffness and hysteretic energy. Based on those results, we obtained the ductility coefficients, behaviour factors, and equivalent damping coefficients of the RC frames with strong infill walls ("frame- wall") and the bare RC frame, all of these variables depending on storey drifts. The experimental and analytical results of frame-wall and RC frames, regarding their lateral capacity and lateral stiffness, were compared. Experiments showed that the masonry infill contributed to the lateral capacity, lateral stiffness, hysteretic energy, changed behaviour, as well as the equivalent damping coefficient of RC frames. It is shown that "frame-wall" composite behaved as full- fledged building type having lower vulnerability than RC frames and enough displacement capacity to sustain displacement cycles in the nonlinear range of response.
