Analysis and Design of Cable Stayed Bridge Abstract Of the newly-built bridges, cable-stayed bridges are today very common worldwide for spans ranging between 200 and 900 meters. A cable stayed bridge has one or more towers (Pylons) from which the cables support the deck. This paper provides modelling, analysis and design of a prestressed harp type single pylon cable stayed bridge using MIDAS Civil. Keywords: cable stayed, box girder, prestressing, MIDAS Civil Introduction Of the newly-built bridges, cable-stayed bridges are today very common worldwide for spans ranging between 200 and 900 meters.
