Abstract
One of the effective methods to reduce the seismic response of the adjacent buildings is to connect these buildings by passive dampers. In this research, the seismic performance of this type of control system is evaluated using fragility curves. Furthermore, the parameters and arrangement of the connecting viscous dampers are investigated. For this purpose, two 8- and 12-story RC special moment-resisting frame buildings are connected by viscous dampers. After obtaining the appropriate parameters and arrangement of dampers, incremental dynamic analysis was performed under 22 far-field ground motions using OpenSees software. Assuming a log-normal distribution, the probability of exceedance of the performance level is calculated at each maximum ground acceleration value as a fragility curve. The fragility curves show that the connection of adjacent buildings by viscous dampers will improve the seismic performance of both connected buildings compared to the corresponding results of single uncontrolled buildings.
