The Roxeler Ingenieurgesellschaft (Roxeler Engineering Society) has
been successfully working in engineering for more than 40 years. Our
competences include designing civil, building, environmental and soil
constructions. In order to create economic, aesthetic and sustainable
solutions, we use complex finite element models and intelligent
algorithms. Realistic discretisation of building design taking non-linear
and time-dependent material laws into consideration provides scope for
architectural design beyond normal limitations.

The newly built bicycle underbridge passes under a busy main street in
the town of Doetinchem in the province of Gelderland. The tunnel was
formed using precast elements, weighing up to 50 t each. Geometrically,
these elements are trapezoids with bore dimensions of 750 x 275 cm. The
approach elements on both sides were also built using precast elements.
All elements were sealed by grouting the joints. The soil had very low
bearing capacity, which is why the elements were prestressed to make
the tunnel less sensitive to different ground water levels or soil movement.
Inside the passway, colour-variable lighting was installed, giving it the
nickname of the “disco tunnel” in Dutch media.
All precast reinforced concrete elements were designed using
SCIA Engineer. They were individually calculated as frames. The design
checks for the longitudinal prestressing within the highly loaded middle
part were calculated by modelling the entire system in one finite element
calculation.
