Study of vulnerability and damage: the case study of Castelnuovo after L’Aquila earthquake (Italy)

After the L’Aquila earthquake (04/06/2009), the authors surveyed the building stock of Castelnuovo, a hamlet in the San Pio delle Camere Municipality (L’Aquila). The macroseismic effects reached intensity 9.5 (MCS scale) at Castelnuovo. The shaking caused collapse of 50% of the whole built that includes 102 aggregates and 324 structural units. First of all a brief description of the methodology (with reference to EMS-98 classification) used in the surveys are presented. Then, the main results of the study, in terms of structural typologies and analysis of vulnerability and damage, are defined. By means of the analysis of vulnerability and the geology characteristics of soil, an evaluation of the damage is proposed. Finally in the paper local seismic responses of masonry building aggregates are evaluated: the main results in terms of qualitative classification of out-of-plane mechanisms for the panels are discussed.
