In the paper the usability checks performed on precast RC gyms and masonry school buildings, located in the Municipalities of San Pietro in Casale (BO), Bomporto (MO) and Bondeno (FE) after the seismic events occurred on 2012 May 20th and 29th, are reported and discussed.
First, the main features of surveyed buildings have been identified. Later on, on the basis of the detected damages, their seismic deficiencies have been recognized. Finally, the indication of some appropriate simple interventions for retrofitting studied buildings has been given.

Effective procedures to evaluate the seismic vulnerability of monumental buildings
In this paper, a preliminary study about effective procedures to evaluate the seismic vulnerability of monumental buildings of particular typology (churches) is proposed. The method is able to work out the seismic- acceleration levels related to the different limit states, before and after the possible interventions. This evaluation, feasible for each different macroelement /1/ that a church is typically made of, is in agreement with the seismic-safety procedures proposed by the recent Italian Decree, in case of local mechanisms in masonry existing ordinary buildings. The application of the methodology to two case studies is presented: the church of S. Giovanni Battista in Colletorto (Campobasso, Italy), damaged by the 2002 earthquake, and the church of S. Lazzaro in Foligno (Perugia, Italy), struck by the 1997 seismic events.
