The researchers studied how retrofitting techniques on an old school building in Bucharest improved its ability to withstand earthquakes. They used computer software to model the building's structure and analyzed how different retrofitting methods affected its strength. By comparing the building before and after retrofitting, they found that the interventions significantly improved its seismic safety. This research is important for improving the safety of many old buildings in Romania, especially in the education sector, which are at risk during earthquakes.
