Abstract
During the 2009 L'Aquila earthquake several historical centres (Onna, Castelnuovo, Villa Sant'Angelo,...) were severely struck, with heavy damage extended to the whole built-up areas and collapses of large portions (sometimes even of the totality) of many urban blocks. Because of the entity of damage suffered by these centres, the problem of the possible restoration of their surviving, or little damaged, portions and of the reconstruction of the wide zones completely collapsed, or irreparably damaged, involves the need of handling much more complex situations than those implied in other cases. In fact in these cases, preliminary surveys are prevented, firstly, by the impracticability of streets (or even whole aggregates) and secondly by the precariousness of surviving portions which makes unsafe workers operations. 2 On one of these centres, Villa Sant'Angelo, a research activity has been started by the Universities of Genoa and Catania and the Construction Technologies Institute of L'Aquila (National Research Council - ITC) with the aim of supplying a scientific support for the local administration in managing the post-earthquake actions on the historical centre with the final goal of defining the criteria according to which the possible reconstruction should be carried out. In particular, the paper illustrates the methodology which has been proposed to design the rubble removal planning in order to promote the restoration of surviving portions (costs and safety concepts permitting).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
