Structural Optimizations of Extradosed Cable‐Stayed Bridge by Using Genetic Algorithm

Abstract An extradosed cable‐stayed bridge employs a structure that combines the main elements of both prestressed box girder and bridge. In to apply optimization, because this type has hybrid nature; bridges have significant additional complexity oversizing [7]. This research paper evaluated optimum depth with pylon height, angle stay cable, effect concrete grade on those three parameters an cable‐stay for fixed span length (100+180+100) m. The formulated optimization problem was code into Mat lab R2019a software run using genetic algorithm analysis results retrieved from SAP2000v23 carry out process. indicate less than recommended value depth, height found be more reduce previous work first cable is 32.13o C‐45.
