ARCH 653- MIDTERM PROJECT- L' Oceanografic


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.
