A Review of Response Analysis of two Parallel Buildings Coupled by Nonlinear Damper

In recent years, considerable attention has been paid to research and development of structural control with the use of passive control devices. Fluid viscous dampers are generally well suited to vibration control of civil engineering structures subjected to seismic excitations. The results of several studies on the effects of supplemental viscous damping on the response of structures have showed that they are efficient and very effective in mitigating the seismic energy. The fluid viscous dampers can be classified into linear fluid viscous dampers and nonlinear fluid viscous dampers. The nonlinear fluid viscous dampers are found more suitable than the linear fluid viscous dampers because nonlinear fluid viscous dampers possess the capacity of reducing peak damper force demand at large structural velocities while still provide sufficient supplemental damping. The focus of this review paper is on the structural control of two parallel building structures coupled with nonlinear viscous damper. This paper includes a brief historical outline of the development in structural control with fluid viscous dampers. This paper also includes a brief introduction about the nonlinear fluid viscous damper. The objectives of the present study on the nonlinear fluid viscous damper connecting two parallel buildings are also included in this paper.
