Earthquake structural problems and urgent measures undertaken to support the Katholikon of Dafni Monastery in Athens, Greece

摘要

The Byzantine monastery of Dafni, already inscribed in the world heritage list of UNESCO, is one of the most important monuments of middle Byzantine period, famous worldwide for the excellent mosaics of the Katholikon. Being in a highly seismic area, the monastery suffered throughout its history a large number of earthquakes that caused many structural problems and damages to its mosaics. This presentation focuses on the emergency measures undertaken by the Greek Ministry of Culture after the earthquake of September 7th 1999 in Athens, in order to avoid local collapses and further damages from aftershocks, and ensure safe working conditions for the personnel. The basic philosophy of the urgent interventions and the different temporary shoring and strutting measures, that have finally been realized, are briefly presented.
