ABSTRACT

The design of Kemaliye Bridge, with a total length of 290.0 m and width of 17.0 m, has been carried out by Emay International Engineering and Consultancy Inc. Within the scope of the Project entitled “Design and Engineering Services for Kemaliye and Kozlupınar Bridges located on Kemaliye-Dutluca Road”, implemented by the Client Republic of Turkey, Ministry of Transport, Maritime Affairs and Communications, General Directorate of Highways. The Kemaliye Bridge has 3 spans with 140.0 m. central span length and side spans each of 75.0 m length. As measured from the top level of the foundations, the pier heights are 60.0 m each. The bridge deck has been designed as prestressed post-tensioned concrete by cantilever method. The segment lengths are 3.0 m, 4.0 m, and 5.0 m. The depth of the box girder deck varies between 8.50 m on piers and 3.50 m at midspan.

During the design stage of the Kemaliye Bridge, which will be constructed by the balanced cantilever method, deflections and calculations involving time dependent factors such as creep and shrinkage have been carried out following the completion of each segment. Furthermore, losses in cable prestressing forces due to various factors (creep, shrinkage, elastic loss, relaxation, friction, anchor set) and also stresses and deformations due to uniform temperature differences (thermal gradient) have been taken into account in the calculations.

The environmental effects of the construction of the bridge have been minimized by virtue of the balanced cantilever method of construction, and following the completion of the construction work, an esthetic and elegant structure will emerge which will be harmonious with the environmental scenery and attractions.
