The role of flat-jack testing after recent earthquakes

In this paper, the main focus is on determining the material characteristics of the existing unreinforced masonry buildings. The paper briefly describes the method of testing masonry using flat jacks. The method belongs to the semi-destructive tests and has been used in civil engineering since the end of the 20th century. Also, the results obtained from in-situ tests on several buildings in Zagreb and the surrounding area after the recent devastating earthquakes in Croatia in 2020 are graphically presented in the last chapter. The results obtained in this way serve as a basis for further design. Investigative work is necessary for quality assessment and renovation of existing buildings, many of which are under cultural protection and deserve special care. In this way, management of the existing building fond is more economical and sustainable. Also, buildings are becoming safer and more reliable.
