For the purpose of the CEVISAMA 2020 Fair, the MaP + S group, belonging to the Harvard Graduate School of Design, has designed a ceramic sculptural ensemble that was placed at the entrance to the main pavilion of Valencia´s exhibition centre.

The system is made up of two levels of ceramic struts, with a 250x60mm hollow section and variable length, that pivot around a vertical axis, with the intention of generating ruled surfaces. It consists of four modules, two on each level and symmetrical with respect to the central axis of the sculpture.

Each of the two levels has a height of more than 3 meters. The ceramic pieces have been connected to each other by metal plates. In addition, the sculpture is arranged on a support and leveling platform to properly rest on the floor of the exhibition centre.

The natural behavior of the ceramic struts would cause bending stresses in the ceramic, a stress that said material can hardly bear. For this reason, it was proposed to compensate these efforts by means of tensile forces applied to corrugated steel bars. These bars, placed inside each of the ceramic pieces, have allowed us to control the way the elements work, working the set only against axial stresses. The tensioning on the bars was carried out using threaded parts, the tightening of which was previously controlled by deformation of the material itself.

Windmill's work has consisted of the structural verification of the overall stability of the set, as well as the calculation of the strength of the joints and the tensile strength of the ceramic pieces. Additionally, it´s level of safety with regards to overturning and sliding in an accidental situation has been evaluated, to avoid the collapse of the structure in the event that any visitor impacted on it during the course of the fair, and the correct execution and assembly of the structure prior to the opening of the event.
