Infill structures consisting of reinforce concrete (RC) frame and masonry infill walls are very popular structures, especially in seismic areas. In such structures, RC skeleton plays load-bearing role and infill walls play significant role as secondary elements stiffening the entire building during earthquakes, when they are in good shape and structural condition. Their damages lead to reducing of stiffness and thus to reducing of seismic resistance of RC frame structures with infills. They should also be resistant to cyclically repeating earthquakes to reduce economic losses. In this paper, innovative solutions protecting infill structures are presented with results of their examination on a shake table, and especially damage and stiffness parameters changing with repeating seismic excitations are discussed. Their analysis confirmed that these introduced anti-seismic solutions based on flexible bonding are able to protect infill structures against serious damage and failure (in-plane or out-of-plane) and protect RC columns against damages under repeating strong seismic action, assuring safe level of load bearing capacity. Obtained results indicate that these antiseismic solutions can be used efficiently in damaged or newly constructed infill structures in seismic areas.
