Abstract

Cable stayed bridge is the demand of every nation and it could be achieved with use of enhanced materials. Generally, cable supported bridges comprise both suspension and cable-stayed bridge. Cable supported bridges are flexible in behaviour. These flexible systems are susceptible to the dynamic effects of wind and earthquake loads. Here focus is given on the effect of shape of pylon on the seismic response of cable stayed bridge, for this, the bridge span dimension and other parameters are kept constant, and only the pylon shape is varied viz. A type, H shape and inverted Y shape. The height of the pylon is kept constant for all the shapes for comparison purpose. The 3D bridge model is preparing on ANSYS software and bridge is analyzing seismically. Straight and curved cable stayed bridges are analysed to study the seismic behaviour and effect of pylon shape of both.
