The European Centre on the Vulnerability of Industrial and Lifeline Systems, from North Macedonia organised a workshop on the "Seismic Assessment and Retrofitting of Masonry and Preserved Structures" on 23 May 2024, in Skopje. The workshop constituted another milestone of a joint project implemented in cooperation with the European Centre on Prevention and Forecasting of Earthquakes, from Athens, Greece. In addition to the exchange of know-how at this workshop, both centres working together under the aegis of the EUR-OPA Network of Scientific Centres, collected preliminary data from masonry and preserved structures in North Macedonia and discussed the lessons learned from the implementation of the new Greek Code on Seismic assessment and retrofitting of masonry structures (KAΔΕΤ).
