These buildings are affected by a ll typologies of damages such as cracks, widespreadand local collapses, total destruction. Marche region is the most affectedarea with n.51buildings (the 48%of total), while the other three regions have a similar percentage of churches identified as shown in the following table. 107

2. Framework on artworkdamagedby August 24, 2016 earthquake From the survey carried out by the technicians of the Crisis Units of the MiBACT, a damage framework shows approximately 20.000historical-artistic and archaeological artworks, over 4.500 linearmeters of archival goods and 10.000 volumes of book goods. 2.1. Religious artworks damages as churches’ contents The historica l artworks a llocated intochurches affected byearthquakes of 24 August 2016, are characterizedbya grea t varietyof size, typology and materials: frescoes, canvases, statues, portals, a ltars, holy wa ter fonts, tabernacles, baptismal fonts, choirs, fa lse ceilings, decorative structures, etc. Furthermore, considering these historical-artistic assets in rela tion to their Church-container, a further differentiation is shown considering their connection with structure. In fact, the most complexaspect connected to the church “ container ” is tha t in addition to movable assets, there are another two main categories regarding immovable artistic assets. It is possible to find: • Structural elements with anartistic value owing to decoration (e.g. carved stone columns). • Non-structural artistic elements that are somehowconnected to the construction (e.g. frescos, plasters, pinnacles). (Marra , 2015) • Movable historical artistic assets characterizedby no connection with structure. These different categories are susceptible to specific types of damage due to earthquake, dependingon their own na ture. Structural elements mayoccur damages considered for architectonic assets, non-structural elements may occur different kind of damage: if they are strictly connected to structural elements case the damage depends on the behaviour of thestructural elements theyarea ttached to, if theyhave a own seismic response, the damage depends on the connections with the supporting structure: • direct connection (DC) resultingby execution techniques such as stuccos and frescoes; • punctually or continuouslyconnection (PC), such as a ltars and holy wa ter fonts; • isolated and easilyremovable elements (NC), such as statues andcanvases. These la tter represent the real movable historical andartistic goods.
