Past and recent investigations of colliding structures under seismic excitation confirmed that pounding may have a significant influence on the structural response. Interactions between adjacent buildings may cause serious damage to the structures, leading even to its total collapse. The main reason of earthquake-induced pounding, besides insufficient distance between structures, are differences in stiffness or mass of colliding structures. The aim of this study is to show the results of experimental analysis focused on structural pounding between insufficiently separated buildings under earthquake excitation. To perform this study, models of three steel towers, with different dynamic parameters were constructed and mounted to the platform of a shaking table. The influence of rubber and styrofoam bumpers located in gap (=30 mm) was taken under consideration. Analyses were performed to answer the question if putting bumpers between two adjacent structures may prevent damage which were the result of pounding. Experimental study confirmed that earthquake-induced pounding may lead to changes of structural behaviour. Additionally, use of bumpers may lead to the decrease of structural response, as well as its increase, but the pattern of changes is not constant.
