This is a project of a road flyover above a railway. The structure is divided
in three main parts: two abutments in reinforced concrete and the flyover
made of prestressed concrete. The total length of the project is 397.30 m.
The project is formed by three hyperstatic sections. The first section is
composed by three spans of 35 m. The second section by three spans of
44.8 m, 48 m and 44 m. The third section is smaller and formed by two
spans of 30 m.
SCIA Engineer
was used for calculation of the structure. This software
has a user-friendly interface and fulfills our main challenges for
hyperstatics precast flyovers.
Allplan Engineering
was used to produce
drawings of the project, and we obtained fast results of detailing and
precision in calculating material quantities.
The main challenges faced were the interferences found on site. As
the flyover is above a railway, interferences of electrical grids had to
be considered, imposing a small template for construction and less
expropriation area. Another challenge was that the railway could not be
stopped for construction of the flyover, so it was necessary to calculate
steel shorings.
The project was finalized on time and by using Nemetschek Group
software we had great productivity in detailing and calculation.
