For the structural analysis we decided to play with the geometry of a vault linked to certain parameters that were able to change the physical appearance of the whole piece. In the first case, we have a regular vault without any change. The height is 4m and the length is 8 meters. For the second and the third cases, the ideas was to deform the middle point of the of the arches that control the shape of the vault. The following analysis of each one of the cases, shows a progressive complexity increase of loads and support distribution. Our idea was to evolve the analysis in six steps, starting with just one single vertical punctual load and 4 supports, till the most complex one with loads in different directions and more supports without any degree of freedom.
