Abstract: In this paper, effects of various parameters such as geometric properties of deck and pylon and number of cables on the behaviour of cable stayed bridge were observed. For this purpose, analysis of 240 m long fan type cable stayed bridge having single plane of cables is carried out with the help of software facilities. To save time in modelling of bridges manually, a programming tool has been developed in excel software with the help of visual basic macro for the purpose of parametric study of Cable stayed bridge. With the help of this tool, number of models of cable-stayed bridge can be automatically generated in software SAP-2000. From the analysis of number of models, comparison of bending moments in pylon and deck is done.
