A steel and concrete engineering
company
Stendess can vouch for the total stability
analysis of projects.
Our approach covers
the initial study trough to the end project.
With its in-house know-how in steel as well
as concrete, the firm is able to offer full study
pack-ages for both materials.
Thanks to its accumulated know-how and
its advanced infrastructure, Stendess can fol-
low up on cross-border projects in accor-
dance
with
most standards and codes:
Eurocode,
NBN,
NEN,
DIN,
NF,
AISC, British
Stan-dards and specific national codes.

Short description of the project
It concerns the realization of 4 identical gas
fired combined cycle power plants in Castel-
nou, Spain.
The steel structure had to be designed to
support a total equipment weight of ± 2000
tonnes and a total piping
weight of 1250
tonnes.
About 80% of this weight is situated
at a height of ± 30 m. The
whole project
was situated in a seismic dangerous zone
and a high wind speed zone.
Use of ESA-Prima Win
Description of technical questions
solved by ESA-Prima Win
The challenge in this project was to design
a low budget supporting steel structure for
a gas fired combined cycle power plant
which was situated in a seismic dangerous
and high
wind speed zone and of
which
the to be supported weight (± 2250 tonnes)
was situated at a high level above the
ground (± 30 m),
which is very defavorable
in a seismic zone.
The simulation of the seismic actions
was
done by static equivalent horizontal loads in
accordance to the natural frequency of the
structure.
Finding the balance between a relatively
low stiffness of the whole structure (in order
to decrease the seismic impact) and a suffi-
cient supporting structure with expectable
deformations was a high creative demand
in the static layout and the dimensioning of
the structure.
Description of our experience with ESA-
Prima Win when realizing the project
For this project ESA-Prima Win proved its
power to calculate at high speed large
structures with a great number of bars and
a great number of combinations.
More, ESA-Prima Win proved that even for
large structures the dynamic calculations
could be done in an acceptable
way and
time.
Even optimisation of such large structure
didn’t give much problems.
