In the past few decades current EQ resistant design practice of RC framed structures effect of brick infills is neglected and infills are considered as non structural member. Performance of structures in past earthquakes and significant research expended in studying the behaviour of masonry infilled RC frames show that the infills enhance the in-plane lateral stiffness and strength of the reinforced concrete frames. In literature, most of the experimental work on infilled frames is focused on monotonic loading. And, in most of the work reported on behaviour of infilled frames under cyclic loading, attention is drawn primarily to the effect of various strengthening techniques and types of infills on lateral strength and lateral stiffness of the frame. In particular, very little work has been reported on the behaviour of infilled frames in India under reversed cyclic loading. So, in this study, cyclic testing of infilled frames is carried out to help the process of development of design guidelines for RC frames in India, which requires extensive experimental data. In the
