Validating Thrust Network Analysis Using 3D-Printed, Structural Models

"That the behaviour of masonry structures is only a matter of geometry, and not of stresses, makes their behaviour independent of scale. This powerful notion made it possible for [...] master builders to push the limits of imagination over centuries of evolution of form. They could use geometric rules, which allowed them to copy the geometry of successful precedents and to scale them up; and scale models, which allowed them to check the stability of vaulted creations and to carefully balance them where necessary by adding blocks on the extrados."
