Sažetak
The Old City of Dubrovnik historical urban heritage architecture, consisted of poorly to well-built irregular stone masonry construction, is at high risk of earthquakes. It is enlisted as the UNESCO World Heritage after severely damaging 1979 Mw=7 Montenegro earthquake. Retrofitting strate-gies to a certain degree of earthquake protection have been made to the monument heritage ar-chitecture after repeating destructive earthquakes for several centuries. The originally 13th century Rector’s Palace underwent several major modifications throughout history after disastrous events, which were: fire in 1435, gunpowder explosion in 1463, earthquakes in 1520, 1667, and in 1979. The design and construction information was collected from historical records and studies per-formed by various researchers including field measurements and laboratory tests. Based on the data gathered, the building's resistance to destructive earthquakes in compliance with contempo-rary building codes was determined by using simulations on a calibrated spatial structural model. The study revealed the building’s critical parts most susceptible to some degree of damage or col-lapse. Presented case study is the basis for decision-making and the implementation of building’s earthquake risk reduction measures. Additionally, it will serve as a guide for earthquake risk evaluation on similar buildings, even though they may differ in degree or detail.
