Paper Abstract

Two adjacent parallel building structures are connected by control devices including stiffness and damping components. These building structures are currently used in engineering since the control devices may reduce the dynamic responses in earthquake and wind excitation. But the connecting stiffness may chance dynamic characteristics of whole building and the coupling between two structures should be considered. In this paper, a new optimal design method for twostructure connection control system is proposed. The mathematical model of two-structure connection control system is established only including the damping components. The optimal parameters of dampers can be obtained by using the simplex optimal method with the performance index J in frequency domain. A new performance index ▵J of control devices is also proposed to obtain the optimal number and placement of control dampers. Numerical results illustrate that the proposed optimal design method is effective and flexible. It may properly utilize the interaction between two structures and the control devices to reduce the response of buildings.
