Using fluid dampers to connect adjacent buildings for enhancing their seismic resistantperformance has been recently investigated but limited to linear elastic adjacent buildings only. This paperpresents a study of inelastic seismic response of adjacent buildings linked by fluid dampers. A nonlinearfinite element planar model using plastic beam element is first constructed to simulate two steel framesconnected by fluid dampers. Computed linear elastic seismic responses of the two steel frames with andwithout fluid dampers under moderate seismic events are then compared with the experimental resultsobtained from shaking table tests. Finally, elastic-plastic seismic responses of the two steel frames withand without fluid dampers are extensively computed, and the fluid damper performance on controllinginelastic seismic response of the two steel frames is assesed. The effects of the fundamental frequencyratio and structural damping ratio of the two steel frames on the damper performance are also examined.The results show that not only in linear elastic stage but also in inelastic stage, the seismic resistantperformance of the two steel frames of diferent fundamental frequencies can be significantly enhanced ifthey are properly linked by fluid dampers of appropriate parameters.
