Abstract (EN): This paper deals with the construction of cable-stayed bridges by the process of successive advances, with a concrete deck achieved by in-situ concreting. A case study of a cable-stayed bridge built in Brazil is presented, which analyzes the response of the structure under distinct evolutionary construction phases and in-service phase. In the analysis of the construction process it was considered the evolutionary character of the structure, verifying the structural system response in terms of generalized forces and strains. The analysis focused on variants of the method of successive advances to build the bridge deck. One of the analyzed variants is the application of OPS (Organic Pre-stressing System) by implementing an active bolting system that is an alternative to the construction processes currently used. From the analysis of the results it is possible to understand the influence of the selection of the construction process in the bridge deck design. © 2015, Taylor & Francis Group, London.
