New Station in Belval-Usines
The roof of the new station is steel structure composed of 37
portal frames with an elliptic form. The span of the frames
varies between 17 and 31m with a height between 6m and 10m.
The frames are made out hot rolled H profiles and are rigidly
embedded within a longitudinal concrete beam of 1 m height.
Portal frames are connected with tubular longitudinal ele-
ments; wind braces are also made out tubular steel profiles.
The external portal frames will receive a glass façade, fixed on
vertical steel profiles.
To avoid the distortion due to the curvature of the profiles,
dilatation joints are foreseen between the different zones of cur-
vature. The most curved beams shall been realized in welded
reconstituted profiles.
The structure has been modelled in 3D in AutoCAD on basis of
architectural drawings. The calculation model (axis lines) has
been read in SCIA•ESA PT.
We have used the functionalities of
SCIA•ESA PT to finalize the geometry of the axis model. Then
we have attributed the profiles, loads and supports The calcula-
tion model was ready in a few hours.
We have used the design
modules of SCIA•ESA PT to rapidly come to a pre-design of the
structure.
