OBJECTIVE
The objective of this project is to create a structure using
parameters for the building model and facade. The case study I have selected is
L’Oceanografic building in Spain. The architect used thin-shell reinforced
concrete to create his signature hyberbolic parabola structures. The geometry
of the structure was based on the intersection of three lobes that describe the
shape of hypar.

CONCEPTUAL MASS MODEL
The first and the toughest part of this project was to
create a conceptual model to form the shape of the building. The shape of the
building is octagon. The sides of the octagon were parametrically controlled by
the dimensions of the side. The parameter used to create was the internal angle
between the two sides of the octagon. Then the next step was to create a point
at the center of the octagon. I have controlled the placement of this point parametric with the side dimension of the octagon.

Next step, is to create a roof structure. The original roof
structure was in the shape of the parabola. Due to time constraint I adopted
the shape of partial ellipse. The dimensions of the ellipse were parametrically
controlled. The length of the major axis was linked to the side of the octagon.
The length of the minor axis was given a new parameter that controls the height
of roof along the side of the octagon.

MASS-MODEL
Then solid masses were created. The first mass was created
by selecting two radially outward lines and the corresponding partial ellipse
for roof structure. The second mass was
created by only selecting the ellipse for the side wall.

FACADE
The shape of the facade in the original building is
rectangular panel. So I have also used the rectangular panel customizing it with
sloping surfaces. The height of the surfaces, frame thickness and frame width
of my facade can be changed parametrically. I have then loaded this façade parametric
pattern to my conceptual mass model.

PARAMETRIC FAMILIES EXAMPLES
The following figures shown have different parametric values
for the mass family.
Figures 7 and 8 have same dimensions for roof
top and roof height along the side. Side of the octagon parameter has been
changed.
Figures 9 and 10 have same
dimensions for octagon side and roof top. Roof top along the side of the
octagon parameter has been changed.
Figures 11 and 12 have same dimensions for octagon side and roof height along the side.
Roof top parameter has been changed
CONSTRAINTS
The first
constraint was creating octagonal base for my model. I tried various options by
creating a parametric polygon using detail component template. But I was not
able to load into mass model.

The
second constraint was creating hyperbolic parabola roof structure. I have tried
various options to create a parametric parabola linking the side of the
octagon. I created a parametric parabola by choosing each side of octagon as
the reference plane. I selected the vertical plane of the octagon and tried
placing points in the shape of the parabola and then joining them using spline.
I could join the points on the four sides of the octagon which were on north,
south, east and west directions. However I couldn’t change the other four sides
as I couldn’t access the elevations of the north-west, north-east, south-west
and south-east.
