The behavior of cable-stayed bridges having different cable arrangements under static and dynamic loads

Cable-stayed bridges have recently been preferred to cross middle or large size spans because of having high capacity of load-carrying, low cost, esthetic look and short building periods. As the population grows, number of vehicles and necessity of motorways for transportation grow as well. In the projects, bridges are designed containing two or three decks instead of one large deck. In this study, behavior fan shaped, harp shaped and semi-harp type cable-stayed, with double deck, bridges having the same condition of deck, tower and support were examined.
