Abstract
The requirement of large span bridges increases with the development in every nation. Cable stayed suspension hybrid bridge could be acceptable choice as long span bridges. The reason of this study is to find Response Reduction Factor (R) of this type of bridge with different type of pylon shapes using midas Civil software. Nonlinear Static Analysis is carried out to determine this factor. The ‘R’ factor is applied to base shear of the bridge for economical bridge design. There is no specific value of ‘R’ Factor mention in IRC codes. From the study, it is observed that values of ‘R’ for seismic Zone : II are 6.3884, 4.6880, 7.7322 for H type, Diamond type, A type pylon shape, respectively.
