Figure 9
Out-of-plane mechanisms of the façade macroelement. (a) Mechanism 1: out-of-plane mechanism of the façade; (b) mechanism 2: interaction between the façade and the peripheral lateral walls; (c) mechanism 3: interaction between the façade, the peripheral lateral walls, and the nave walls. Roof structure and surrounding chapels are here hidden to view. Light gray parts in the picture are not part of the mechanism.
