The paper presents dead load analysis of Suspension Bridge and Cable-Stayed Bridge by keeping the parameters such as Main Span, Side Span, Pylon Height, Bridge deck and material properties same. By analysis the optimum sag for suspension bridge at which minimum value of deflection is obtained. Then Suspension bridge is modeled with the optimum sag value and the diameters of main cables are changed and resulted deflection of bridge deck is noted. The diameter for which minimum value of deck deflection is obtained gives the optimum value. The quantity of steel for the resulted optimum sag and optimum diameter is noted. Similar process of changing diameter of cable of Cable-Stayed Bridge is done and optimum diameter is noted. The bridges are modeled in CSI-Bridge Software. The result shows that cable stayed bridge of same length when compared to Suspension bridge uses less steel and also resulting deflection is less.
