Aim: To study the static behavior of cable stayed bridges and effect of various parameter on cable stayed bridge. To carry out comparative study of cable stayed bridges Methodology :In this paper parametric study of cable stayed bridge is carried out. In this study three span, two plane cable stayed bridge with box girder deck is considered. For analysis IRC class AA moving load is considered and its effect on cable stayed bridge girders is studied. Analysis is carried out with help of MIDAS CIVIL software. The various parameters were considered for analysis of cable stayed bridges; those are side span to main span ratio, upper strut height, cable system, number of cables per plane and cable diameter. We have studied the effect of above parameters on maximum girder moment, deflection, shear force, axial force in the girder. Results: With the increase in side to main span ratio maximum moment is decrease up to certain limit and then increases. With increase in number of cables maximum moment in girder decreases. Conclusion: Maximum moment in the girder is reduced for ratio 0.5 by 14.34% as compare to side span to main span ratio 0.35. It is found that maximum moment in girder decreases with increase in number of cables. It decreases by 47.76% for 20 cables per plane as compare to 8 cables per plane. There is no significant change in the maximum moment in girder with increase in cable stiffness.
