Seismic Response Control of Adjacent Buildings Connected by Viscous and Hybrid Dampers
Abstract
This paper discusses the seismic response control of a building by connecting it to another adjacent building. Coupled buildings have demonstrated to be an attractive method to mitigate excessive dynamic responses. This paper studies the behavior of two structures connected by passive dampers and also considering local feedback control systems installed in each structure, an hybrid strategy. These feedback control systems are designed and operated independently using active devices with limited actuation capacity like force actuators. The governing differential equations of motion of the coupled system are derived and solved for relative displacement. The advantages and disadvantages of each control strategy are examined in order to determine the more appropriate one. Based on the present research results, general conclusions and recommendations are given for further studies.
