The paper is focused on the the safety evaluation of domes applying a modern numerical method based on the model of elastic no-tension material. The proposed method looks for a compressive thrust surface S, in equilibrium with the applied loads, contained within the extrados and the intrados surfaces of the structure. The membrane S is partitioned in two regions: one in biaxial regime, another in uniaxial regime.The boundary between the regions is unknown and depending on the external loads. The method is applied to the case study of the St. Gennaro dome. The dome has a double cap with non-parallel generatrix curves and is characterized by a fissure outline quite widespread, in both the caps, with the presence of various types of cracks.

Abstract
The paper is focused on the the safety evaluation of domes applying a modern numerical method based on the model of elastic no-tension material. The proposed method looks for a compressive thrust surface S, in equilibrium with the applied loads, contained within the extrados and the intrados surfaces of the structure. The membrane S is partitioned in two regions: one in biaxial regime, another in uniaxial regime.The boundary between the regions is unknown and depending on the external loads. The method is applied to the case study of the St. Gennaro dome. The dome has a double cap with non-parallel generatrix curves and is characterized by a fissure outline quite widespread, in both the caps, with the presence of various types of cracks.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
