This paper deals with the modelling of Cable Stayed Bridges with different shapes of pylons. The cable stayed bridge is one of the modern bridges which were built for the longer spans. There is a need of study on the effect of shape of pylon on the dynamic response of cable stayed bridge, for this, the bridge span dimension and other parameters are kept constant, and only the pylon shape is varied i.e. A type, H type, inverted Y type, Single pylon, Diamond or Pyramid shapes & Double Diamond or Spread Pylon shapes. The height of the pylon is kept constant for all the shapes for comparison purpose. The modelling of bridge is prepared on SAP 2000 software. For this, the arrangement of cable stay has been taken as semi fan type as well as fan type for the purpose of comparison. The study reveals the following points such as the spacing of cables, the inclination of pylon legs & spacing of intermediate supports which needs to be considered for the modelling of bridge.
