The seismic retrofit (carried out in the period February-March 2006) of the “Our Lady of Tears Shrine” in Siracusa (Italy), made substituting the bear-ings supporting its impressive dome with sliding seismic isolators equipped with elasto-plastic dissipators, has determined a significant improving of the structural behaviour.

Abstract
The seismic retrofit (carried out in the period February-March 2006) of the “Our Lady of Tears Shrine” in Siracusa (Italy), made substituting the bear-ings supporting its impressive dome with sliding seismic isolators equipped with elasto-plastic dissipators, has determined a significant improving of the structural behaviour. After a brief description of the new anti-seismic devices, installed between the 22 columns of the structure and the truncated-conical dome, the raising and lowering phases are examined briefly. The seismic re-trofit is shown through the results of a numerical investigation of the Sanctuary under seismic excitation compatible with the news Italian seismic code.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
