摘要

The paper describes the seismic retrofit (carried out in the period February to March 2006) of the 'Our Lady of Tears Shrine' in Syracuse (Italy), made bysubstituting the bearings supporting its impressive dome with sliding seismic isolators equipped with elasto-plastic dissipators. After an accurate description of the construction and of its new antiseismic devices, installed between the dome and its 22 supporting columns, the dome raising and lowering phases, together with the instrumentation and data acquired during the operations, are reported in detail. The improvement of the structural behaviour after the seismic retrofit is demonstrated through the results of a numerical investigation under seismic excitation. Finally, the rehabilitation and reactivation of the pre-existing continuous monitoring system of the temple is examined. The structure has been recently included among those of the Italian network of buildings and bridges permanently monitored by the Italian Department of Civil Protection.
