VSH Turòa nad Bodvou - Nemetschek Scia

The goal of this pedestrian bridge is to connect the two parts of
the woods and the heath land; they are actually separated by a
national trunk road.
The concept of the structure is such, that it is also accessible for
wheelchair-users. The local authorities insist that the form of the
construction is in harmony with the environment.
The engineering office in charge is A+D Engels N.V. - Dieplaan 55
– B 3600 Genk (Belgium).
Description of the structure
The lenght of the structure is total ± 190 m, with an efficient width
of about 2.50 m - is imposed by the profile of the terrain and the
necessary free height above the national road. The distance
between the platforms (walk-overs and turning) is maximum 10 m.
The total weight of the bridge construction is ± 60 ton.
The connecting elements between the different platforms have an
inclination of max. 5% and are alternally connected as continuous
and hinged elements.
The maximal useful height under the structure is 4.50 m at the
height of the bow-bridge over the road. In this position, also a
“viewpoint” is positioned.
The road surface of the bridge is dimensioned for overloads of
5 kN/m2 .
Protection and materials
The complete structure is built with RHS (rectangular hollow steel
sections) A.E.355 D.
The protection of the steel is executed by a high-quality blast and
painting, installed in the workshop.
The breast wall with handles, armour plate and double kneesupports
are executed in rustproof steel.
The floor covering is composed of indelible wooden strips, with
anti-skit ribs.
Use of SCIA-software
We used the ESA-Prima Win software to create the model with
beams and finite elements in a complete 3D environment.
Working with ESA-Prima Win is simple and powerful and the interpretation
of results is clear.
We mainly used ESA-Prima Win to determine the internal forces
and stresses in the steel sections, and to optimisee them according
EC3-prescriptions.
