Fracture mechanics for the reconstruction of Noto Cathedral

摘要

The baroque buildings of Sicily should be ideal subjects of Fracture Mechanics, having heights up to 60 m, PGA up to 0.30 X g, low strengths, few reinforcements, aggregate with irregular stones in the most vulnerable zones. Their analysis constitutes a severe test. The damages between the earthquake on 13.12.1990 and its collapse on 13.03.1996 are due to cracking development always. A monotonic static analysis by FE is performed here. Prestressing and lightening are examined.
