Abstract

The idea to apply temporary and precautionary seismic reinforcements to protect artistic assets in historical buildings is hereby presented. The example of the San Frediano Church in Pisa is addressed to show the improvements in its seismic response due to steel wire ropes applied to arches and columns. Numerical analysis demonstrate the reduction of the shear force at the base of the stone columns. The proposed reinforcements are reversible, temporary and with low aesthetic impact: they can be quickly installed in the beginning of seismic events, as an evolution of the techniques adopted after the last Italian earthquakes (Abruzzo 2009 Emilia 2012).
