Additive Stereotomy

Additive Stereotomy is a proposal by Maurizio Barberio and Micaela Colella of Barberio Colella ARC, developed with the support of Diederik Veenendaal of Summum Engineering.

The overall concept is to cover a large, open space by a series of adjacent arches. Under permanent load, the arches are thought to be statically independent to form a sort of false vault. By using Grasshopper, Summum Engineering determined the shape of the arches and volume fraction of the voussoirs to achieve constant stress, as well as the amount of prestress to keep them in compression under external load. Material properties are based on the 3D printing technology provided by Concr3de and were used in plug-in Karamba3d to check the arches for several load combinations. Each voussoir is topologically optimized in 2D to achieve a volume fraction specific to its position in the arch, to achieve constant stress, yet with a visually similar sizing.
