The paper reports the results of a recent experimental survey aimed to assess the static and dynamic behaviour of the masonry Dome of the Siena Cathedral (Italy), an irregular polygonal masonry structure built in the 13th century constituted by two masonry shells: an internal (structural) dome and an external (covering) dome. The research was motivated by the failure of some elements of the internal stone-truss system which connects the two masonry shells. Reported data represent the main results obtained from an in-situ survey composed by: a) single and double flat-jack tests in the internal dome to assess the internal stresses and the elastic modulus of masonry material and b) dynamic vibration tests under environmental (wind) and artificial (vibrodine) load.

Abstract

The paper reports the results of a recent experimental survey aimed to assess the static and dynamic behaviour of the masonry Dome of the Siena Cathedral (Italy), an irregular polygonal masonry structure built in the 13th century constituted by two masonry shells: an internal (structural) dome and an external (covering) dome. The research was motivated by the failure of some elements of the internal stone-truss system which connects the two masonry shells. Reported data represent the main results obtained from an in-situ survey composed by: a) single and double flat-jack tests in the internal dome to assess the internal stresses and the elastic modulus of masonry material and b) dynamic vibration tests under environmental (wind) and artificial (vibrodine) load. Results of the experimental survey are valuable to a first assessment of the building safety, and to fit a numerical model able to reproduce, as close as possible, the actual behaviour of the Dome. At the end of the paper a brief description of the numerical results are reported. These results, joined with the experimental campaign, allowed for a preliminary evaluation of the Dome static safety, taking into account the observed failure of the stone-truss system
