Why is this project important?
This project is a
multiple-use tower in the inner city of
Eindhoven. It combines the entrance to an underground
parking, shops, offices and apartments.
With a height of
105 meters it will be the tallest building in Eindhoven.
Why is this project so special?
The different functions each have their own type of
construction. The entrance to the underground parking
causes a large gap in the base of the structure. The shops
and offices have high arcades with large columns and the
living quarters have a scattered pattern of windows. The
combination of these different construction-types makes a
program like ESA Prima Win very useful.
Use of ESA-Prima Win
Description of the technical questions to be solved
with ESA-Prima Win:
The main-construction of this tower combines the stiffness
of the core
with the stiffness of the façade (core-tube
system).
The core itself is too slender to supply enough stiffness to
the building. For this reason the core is connected to the
façade by outrigger-walls.
These outrigger walls can't be placed on each floor. The
forces from these outriggers differ from level to level. The
forces from these outriggers have to be spread into the
façade. This was complicated by the scattered pattern of
windows in the façade.
ESA
3D-shell
gives the
opportunity to analyse the
membrane forces in this
complex structure.
On the lower levels the architect wants to create a classic
and inspiring entrance
with large arcades. The spread
forces in the façade at the apartment-levels have to be
concentrated into the large columns of the arcades.
Only
a finite element program (3D Shell) can accurately
calculate the ratio of the forces in the columns.
The forces on the foundation-piles can easily be obtained
by drawing a plate with a pattern of supports. By moving
the supports it is possible to optimise the foundation and
to make sure that each foundation-pile takes the load that
it is designed for.
A description of your experience with ESA-Prima
Win when realizing the project:
ESA Prima win gives an excellent opportunity to analyse
the distribution of forces in the walls and columns. It gives
an accurate estimation of the deformation of the structure
due to the wind-forces.
After the model is completed you
get an integrated total design of the construction. The
only difficulty is to adapt the structure to changing
architectural demands during the design-process of the
tower.
