Experimental Structures Seminar Final Presentations, March 11th

admin — Mon, 11 Mar 2013 15:45:52 +0000

Tonight in IAAC will take place the Final Presentation of the Experimental Structures Seminar.

The aim of the seminar was to investigate the extreme possibilities of textile constructions and structures which make them possible. Starting from analyzing existing technologies, students studied the possibilities of building portable and packable pavilions.

Three models in a 1:1 scale and two models in 1:2 scale have been built and will be presented today at IaaC facilities with the collaboration of SERGE FERRARI and IASO

Directors of the Seminar: Josep Miàs + Silvia Brandi

Students: Zeynep Birgönül, Jin Shihui, Anand Singh, Diego Arturo Diaz Garcia, Dirce Medina Patatuchi, Venkata Kasi Raju Alluri, Georgios Angelou, Juan Diego Ardila, Drew Carson, Jean Akanish, Anca Simona Horvath, Dori Sadan, Maria Kuptsova, Boleslaw Musierowicz, Surag Viswanathan Iyer, Moritz Begle, Diego Colinas Magana, Amir Reza Saheb, Taruni Aggarwal, Aishwarya Sampath, Roopa Sharma, Boghani Harsh Shailesh, Marjan Jelveh Nejad, Angeliki Terezaki, Amir Asayesh, Ibrahim Berkay Ogunc, Elif Gungor, Shivaranjani Kumbar, Priyanka Narula, Kismir Selcuk, Amit Kumar, Miguel Oliveira, Youssef Rashdan.

EXPERIMENTAL STRUCTURES SEMINAR – CONSTRUCTION WEEKEND WORKSHOP

This weekend we had an intensive workshop at IAAC building our 1:1 pavilions for the experimental structures course. Next Monday the 11th of March there will be the final presentation.

In this experiment we tried to build a physical model of a free form surface, using the technique of the geodesic curves of the surface.

The general definition of the geodesic curves is: “the shortes path between points on a surface” but an other definition, describes them on a more efficient way : “being γ(s) a geodesic on a surface X, and A a point on γ(s), the curvature of γ(s) in A is the minimum possible curvature among all curves passing through A and having the same tangent line of γ(s) in A”(Hilbert/Cohn-Vossen).

With few words, this means that in every point of the geodesic curve, the normal vector of the surface on that point is perpendicular also with the curve. Fact that simplifies a lot the joints, wich result all the same and very simple.

We started from choosing the type of surface to use and we decided to try a complex surface wich would include multiple curvatures.

This would permit us to verify the potential of this technique on surfaces that present positive and negative curvature.

With the help of Grasshopper plugin for Rhino we created a definition that made possible testing different situations and see the result of the geodesic curves generated immediatelly.

The Experimental Folds

Carrying on from our previous experiments on Rigid Origami, 2 groups of us have decided to combine forces in making a real scale furniture prototype in order to further experiment on the same technique. Thru this exercise we aimed to be particular in the strategies in the appropiate uses of folding angles in the terms of the object’s functions, the materiality as well as the fabrication techinique.
