The application and effectiveness of seismic response control with variable viscous dampers for nonlinear isolated bridges is studied. Upon considering practical applications, the LQR optimal control algorithm is used to command variable viscous dampers. A typical viaduct is analyzed for evaluation. Through numerical simulation, the results show that the semi-active control system with variable dampers is effective for reducing the seismic displacement response and provides the similar performance by LQR active control with actuators.
