Abstract：Performance-based optimal arrangement of Maxwell dampers between two adjacent reinforced concrete frame structures was studied.The minimum total exceeding probability of two adjacent structures was taken as the optimization objective.The optimal arranging positions of Maxwell dampers between two adjacent structures under the conditions of some certain numbers of dampers were firstly studied.The general arranging laws for optimal positions of Maxwell dampers between two adjacent structures were obtained.Through the seismic fragility analyses of two adjacent structures connected using Maxwell dampers with different optimal arranging positions,the optimal numbers of Maxwell dampers used to connect two adjacent structures were determined.The results showed that the proposed optimal arrangements of Maxwell dampers between two adjacent structures has better control effects for two adjacent structures under earthquakes with different performance targets; the results provide a helpful reference for further engineering applications.
