A linear evaluation model based on dead load deformed structure is arrived at by non linear static analysis. The model is reduced by static condensation. The reduced model is validated with transfer function to match its dynamic response with the original model. The model is transferred to state space and is further reduced with balance realization. This reduction is validated with transfer function again. Two active controllers, one against uniform support excitation and the other against multiple support excitations have been designed to control the response of the bridge against three representative earthquakes. Multiple support excitation case is considered with different angles of attack of earthquake excitation and corresponding time lag of incidence of earthquake wave in different supports. Performances of the controllers are checked by their efficiencies in reducing the peak pylon forces. It has been observed that the active controllers perform well against these criteria. .
