This paper presents the results, in terms of forces and displacements, during the construction process of a cable-stayed bridge over the Dâmboviţa River in Bucharest.
To determine the stress-strain state in the structural elements, a 3D finite element analysis model was developed. For modeling the superstructure, a planar grillage was created and finite elements used were straight space beams with two nodes and six degrees of freedom for each node: three translations and three rotations. To model the concrete slab, plane finite elements with 4 nodes were used, exhibiting both plate and membrane behavior.
In the static analyses conducted considering the construction stages, characteristic and frequent actions were considered according to Eurocode standards for load combinations. The main purpose of the conducted analyses was to monitor the internal forces and displacements in both, the cables and the superstructure elements, as well as in the pylons and their foundations.
The results of the nonlinear analyses conducted in construction stages have indicated that the chosen construction technology is suitable, and the safety level achieved for the structure is appropriate.
