Abstract
Cable stayed bridge are getting more popular these days because of good stability and elegant for long span bridges compared to other types of bridges. A cable stayed bridge is a bridge in which the weight of the deck is supported by a number of cables running directly to one or more towers. Here focus is given on the effect of various shapes of pylons such as Single pylon, A type pylon and Inverted Y type pylon on the seismic response of cable stayed bridge. The effect of various heights of pylons on the seismic response of cable stayed bridge also taken in account for study.
The bridge span dimensions and other parameters are kept constant and only variation in shape and height of pylon is done for comparative study of pylon. The 3D bridge model is prepared on Midas Civil and linear dynamic analysis is carried out. The bridge response in terms of cable forces, pylon deformation, deck deformation, time period and base shear is obtained. It is found that, Single pylon and Inverted Y type pylon are better than A type pylon for parameters cable forces, pylon and deck deformation. Single pylon is stronger in longitudinal direction in resisting earthquake force while Inverted Y type pylon is stronger in lateral direction in resisting earthquake force.
