Abstract
Very often, especially in densely-resided areas and city centers, neighboring buildings are constructed very close to each other, without sufficient clearance between them. Thus, during strong earthquakes, structural poundings may occur between adjacent buildings due to deformations of their stories. The current study presents a simple but efficient methodology that can be used to numerically simulate the incorporation of rubber layers between neighboring buildings with relatively narrow seismic gaps in order to act as collision bumpers and mitigate the detrimental effects of earthquake-induced poundings. The efficiency of this potential impact mitigation measure is parametrically investigated considering the case of two neighboring multistory structures subjected to various earthquake excitations. The results indicate that under certain circumstances the incorporation of rubber bumpers in an excising seismic gap can reduce the amplifications of the peak responses of the structures due to pounding.
