Sažetak (engleski)

The paper presents a case-study of a typical residential building in the district Lower town in Zagreb
historical center. The building is the representative example of unreinforced masonry buildings
that were built at the end of nineteenth and at the beginning of twentieth century. Many buildings
of this typology, as well as the case-study building, suffered moderate to severe damage due to
ML5.5 earthquake that struck Zagreb in March 2020. Due to large number of these buildings, it
is unrealistic to expect their quick replacement with new buildings or even higher investments
in retrofitting to achieve the level of seismic performance prescribed by today’s standards.
Therefore, the modifications were made to Croatian Technical Regulation for Building Structures
concerning seismic requirements. Depending on the building use, a certain level of safety needs
to be fulfilled. There are in total four levels and for the residential buildings, the regulations
propose the so-called Level 2 seismic requirements. Results of numerical analyses based on the
pushover method which are performed to obtain seismic capacity level that is validated with the
proposed demand, are presented in this paper. The seismic capacity of the building is discussed
and necessary strengthening measures for this building typology are recommended.
