Cable stayed bridges are prefered to passing middle and long spaces entire worldbecause of their süperior load-carrying capacity, low cost, aesthetic appearance and short
construction time. Modern cable stayed bridges are constructed three different cable layoutsuch as fan type, harp type and semi-harp type. Because of the increasing vehicle
population, everyday much more raodway to be needed. Hence, new cable stayed bridgeprojects are designed with two or three decks instead of wide decks. For these reasons
above mentioned, there is a research about double deck cable stayed bridges in this study.In the first part of the study is mentioned historical evolution and structural
components of cable stayed bridges and previous researches which related with this study.Especially talked about features of important cable stayed bridges which was built in 20.
century for historical evolution. General informations are given about cables, decks andtowers which are main structural components of cable stayed bridges. Lastly, mentioned
about general and practical calculation of orthotropic decks which often use in bridgeprojects at last years.
The preliminary design stage of three dimensional double deck cable stayed bridgemodels is handled and cross sections of components of models are given in the second part.
In addition to this, loads which apply different cable layout models and geometry ofmodels are presented in this chapter.
İn the third part to obtain differences between double deck cable stayed bridgeswith different cable layouts are analyzed acting static and dynamic loads with SAP2000
computer program and consequences are presented. İzmit-Yarımca earthquake records areused for timehistory analysis.
Finally, obtained results are summarized in the last part of the study and differencesbetween cable stayed bridge models are presented.
Key Word : Double Deck Cable Stayed Bridge, Orthotropic Deck, Cable Stayed BridgeWith Different Cable Layout
