Collection description

This thesis is a part of a comprehensive research program on the study of an innovative ground treatment approach for the mitigation of the seismic risk of existing structure, by means of the creation of a continuous thin layer of grouted soil at a convenient depth. The motivation of the research was the observation of the damage suffered by the historic buildings under earthquakes. In countries like Italy, with a high seismic hazard and old or very old towns, where many buildings are hundreds of years old, this is one of the most relevant problems for the protection of both population and cultural heritage (Costanzo et al., 2007). Few historic buildings meet current code seismic requirements for life safety, and most have architecturally significant elements that are threatened by future earthquakes. The use of the isolation system conceived for new structure could be in conflict with the respect of the iconic, historical and material integrity of the monuments. The present work provides guidance on the use of the soft barriers to seismic isolate the existing buildings, highlighting pros and cons based on experimental and numerical results.
