Cable stayed bridge are the most flexible bridge and getting popularity because of its economy for longer spans and aesthetics. The traditional approach to seismic hazard mitigation is to design structures with sufficient strength capacity and the ability to deform in a ductile manner. Alternatively, newer concepts of structural control have been growing in acceptance as design alternative for earthquake hazard mitigation. The control systems can be used as base isolators to achieve different objectives or performance goals ranging from a life safety standard to a higher standard that would provide damage control. The Primary objective of this study is to improve the performance of cable stayed bridge under seismic loadings. The study enhances using the energy dissipation devices as a promising to passive control technique, to help control the dynamic properties of the bridge structure. Comparison of dynamic behaviour of isolated and Non-Isolated Bridge with and without the Bearing Under three different earthquake motion has been conducted. The 3D bridge model is prepared on CSIBridge software and bridge is analyzed seismically by El-Centro, Loma Prieta and Landers Earthquake. The bridge response in terms of Comparison of different parameters of cable stayed Bridge under seismic loading - time period and natural frequency, Displacement at top of tower, Displacement at mid-point of deck, Moment at tower base Connection with base isolation.
