VSH Turòa nad Bodvou - Nemetschek Scia

The mission of the structural engineering department was to
design the structure of a single level office building, placed on top
of the existing office building. The structure had to be economic
and functional. The erection of the building had to be quick, with
a minimum of inconveniences for the employees working in the
existing office. The architect did not accept any diagonal truss
members in the facades.
After studying several options, the team chose for a steel frame
structure, with two longitudinal main frames, and four transverse
frames. The beams of the transverse frames, whose eight columns
are carrying the whole building, support the steel beams of the
longitudinal frames. The first floor and the roof are designed as
mixed steel plate – concrete floors on transverse steel beams, in
order to reduce the weight of the structure, but keeping enough
mass to ensure a good thermal response of the building. The new
building has a length of 56.70 m, and a width of 13.50 m.
The span (16.00 m) and the overhang (4.00 m) of the longitudinal
beams were considerable. Horizontal stability in both directions
had to be ensured by the framework. The total height of the structure
had to be minimized, as well as the cost of the steel structure.
Esthetical demands and the material used in the facades permitted
only small displacements.
The best approach for us was to use the powerful and easy to handle
SCIA•ESA PT software to build an accurate 3D model of the structure.
The tools in the section manager of the software permitted
us to design some special sections (cross columns in the facades,
build up sections in the transverse frames). The steel check and the
optimisation module allowed us to reduce the weight of the structure.
Displacements were easy to check. Some minor changes could
be brought into the model on a very short notice. The design of
the joints is not yet executed, because the steel constructor is not
known yet, and his vision must be taken into account.
The use of SCIA•ESA PT allowed us to strongly reduce the time and
effort needed to design, in an accurate way, for a not so common
steel frame structure.
