Research on responses of fully infilled RC frames under seismic effects has been active over the last few decades. Nevertheless, the effect of openings in the infills on the nonlinear dynamic responses has seldom been studied. This paper presents a numerical study on the global nonlinear seismic responses of RC frames containing infill walls with three types of openings, namely two-third storey height infills, window-opening infills and door-opening infills. On the basis of the analysis results, it is found that infilled frames with window or door openings exhibit ratchetting phenomena in hysteretic behaviour leading to asymmetric damage and lateral force transfer mechanisms. Furthermore, serious short column phenomenon occurs in the 2/3-storey-height infilled frame structures, in where the central short columns experience serious localised damage resulting significant pinching phenomenon in the hysteretic loops.
