—An attempt has been made to evaluate the performance of ACB masonry in-filled RC frame under cyclic in-plane lateral load. The frame itself was detailed with reinforcement conforming to ductile detailing as per the Indian standards. The specimen tested was a geometrically half-scale model and constructed as per conventional construction practice adopted in India. This means that the RC frame was cast initially, and later the masonry in-fill was provided without making any efforts to induce any structural connection between MI and RC frame interfaces. Obviously, the top of the masonry in-fill and the soffit of the beam remains the first plane of weakness. This also means that the popular diagonal strut action may not be mobilized fully. This should set the guiding principle for any attempt to develop an analytical model for the estimation of failure load. The details of the experimental set-up, the cracking and failure mode of the system and the significance of the experimental response are presented in detail.
