Innovative techniques to increase resistance to earthquakes of cultural heritage buildings and to reduce the impact

Objective


Foreseen Results

The final fall-out of this project should be a global and rational reference plan for the management of conservation actions to achieve maximum safety both for monuments and visitors. The envisaged procedure is largely applicable to other important structural systems, such as dams, bridges and nuclear plants.

The monitoring techniques and restoration procedures can be applied to many countries outside Europe subjected to seismic risk.
The proposed research project is concerned with historical buildings subjected to seismic risk and is meant as a contribution towards the conservation of the cultural heritage, area of mutual interest for all countries. A large number of monuments and significant buildings have suffered from serious damages caused by past earthquakes and are located in critical areas. Although many research activities have been carried out in the field of earthquake engineering, it is felt that a comprehensive approach based on the interaction between non destructive investigations and recent modelling techniques should give an important contribution to the conservation of historical buildings subjected to seismic loads and should lead to identify optimal restoration procedures on a cost effective basis. For the development of the project, two major monuments are proposed : the "Gracarjev turn" castle (near Ljubljana) in Slovenia which was elected national centre of ICOMOS-International Council of Monuments and Sites, by UNESCO and a church in Romania, representing one of the 1200 churches which, at present, are not safeguarded and are often endangered, from the structural point of view, by frequent earthquakes. These monuments are representative examples of difference typologies of the European monuments. Indeed, they are made of masonry, rigid blocks and porolith, so that a wide range of structural models can be considered and studied.

The programme envisages various phases :

* a seismological and geological assessment of the areas
* a geotechnical and geophysical survey of foundations
* an analysis of the structure present conditions (non destructive testing and monitoring techniques)
* application of system identification
* dynamic excitation and prediction of building response to a simulated earthquake.
