Short description of the project
Architectural design
The idea was to build in the Netherlands - land of water -
houses on water. Just like the houseboats, but larger. The
design of this house floating on the water is from architect
Herman Hertzberger.
His first design
was
made in 1986 and thereafter
developed till a villa
with three levels. The location is
Middelburg in the Province of Zeeland.
To
make the house floating, it is placed on large pipes
with a diameter of 2,2 meter and a wall thickness of 18
mm. These pipes are connected together to form a shape
of a hexagon.
On this hexagon, a frame of steel beams is
connected to form a platform for the house. To reduce
loading the house is made of a light steel structure with
wooden floors and walls. The bridge to the wall is used to
fix the house in position.
Structural aspects
The first idea from the architect was to make a triangle of
pipes to float the house. But to stabilize the construction
on the
water, it
was necessary to design a more equal
form. This leads us to the hexagon.
The problem
was to calculate the deformations
while
floating on the water. For that purpose the construction
was based on springs. It is not only the horizontal and
vertical deformation, but also the rotation,
which is
important,
because
of
capsizing
of
the
whole
construction. That was the reason to use Esa-Prima-Win
for three-dimensional structures.
After putting the whole structure in the computer is was
easy to calculate deformations, rotations etc. in each
loading situation. Also it was easy to use the output to
calculate the Eigen Frequency.
Use of ESA-Prima Win
Description of the technical
questions to be solved with ESA-
Prima Win:
The problem
was to calculate the
deformations
while floating on the
water.
For
that
purpose
the
construction was based on springs. It is
not only the horizontal and vertical
deformation, but also the rotation,
which
is
important,
because
of
capsizing of the whole construction.
A description of your experience
with ESA-Prima Win when
realising the project:
Using ESA-Prima
Win gives us the
opportunity to analyze the structure to
find the
deformations to calculate
Eigen Frequency.
Modules used:
Base
2D frame
2D grid
Dynamic document.
Motivation of the jury
Technical level of the design & the calculations:
A good and & detailed analysis, for the calculation of
the
deformations
while floating
on
water the
construction was based on spring foundation.
Originality and prestige:
An uncommon and innovative project but ready for
mass production?
Attractive & complete presentation:
Clear and concise presentation with all info needed &
clear images.
Optimal use of the functionalities:
Appropriate use of the modules.
