In this article, damage assessment of adjacent 3, 5 and 7 storey fixed- and isolated-base steel building frames is evaluated under multiple ground motions. Seismic damage of adjacent buildings has been mostly investigated in previous studies, based on single earthquake by ignoring the influence of repeated earthquake phenomenon and base-condition. In this study, the Park-Ang damage index has been developed in MATLAB platform to quantify the damage level for steel moment-resisting frames. The study concludes that, under multiple ground motions, base-isolators decrease the damage index of 3, 5 and 7 storey adjacent buildings by 57%, 60% and 66%, respectively.
