Lifting – Condominium Via Turati 87 (Italy)

The building has a resistant reinforced concrete frame scheme. with rectangular plan (24.00×10.80 m) and development of 6 floors above ground plus attic. During the earthquake of 06.04.09, the building suffered significant structural damage (class E). A geometric survey and a campaign of experimental tests were carried out to determine the mechanical characteristics of the concrete and steels. The design approach was aimed at comparing the different methods normally adopted for the improvement or seismic adaptation of existing structures: a) strengthening of the sections and local increase of ductility; b) Insertion of bracing elements; c) seismic isolation (cutting pillars at the base or top; elastomeric or sliding isolators). It was decided to proceed with the seismic isolation solution, which makes up for greater executive complexity with the advantage of not requiring general reinforcement operations of the elevated structure.
