The former Isef palace, built in 1938, houses the Gran Sasso Science Institute, the College of Physics, Mathematics and Social Sciences. During the in-depth analysis of the state of the art and the damage suffered following the 2009 earthquake, the widespread presence of cracks and detachments throughout the reinforced concrete structures and the masonry on the outside were well visible, even on the outside. This phenomenon was mostly present on the second level, where almost all the masonry had undergone a rolling outward movement, thus falling out of the reinforced concrete structure.
The assessment of the seismic consolidation of existing buildings was carried out on the basis of the indications provided by the “Technical Standards for Buildings” (Ministerial Decree 14/01/2008). Structural consolidation was the starting point for restoring safety standards and the future use of the building. The project foresaw the demolition and reconstruction of a number of walls using solid brick with reinforced concrete interlocking and brick partition walls on the second and third levels which were seriously damaged. As
far as the external walls were concerned, the demolitions were minimized, and carried out only on irrecoverable or unstable masonry. The remaining brick or stone masonry were reinforced according to an anti-collapsing seam system.
As regards the brick partitions, however, they were demolished and reconstructed with plasterboards, with the exception of the cases indicated in the graphic works. In particular, the restroom partitions were rebuilt with small perforated cement blocks because of the presence of the plumbing system for water services and sanitary appliances
