SUMMARY


Existing unreinforced masonry structures, constructed before the 1960s in the Republic of Serbia and other countries in the region, are at risk of damage or collapse in the event of a damaging earthquake. A significant inventory of such buildings is located in the urban centres of Serbia and other countries. Such buildings usually have residential, public, or mixed commercial and residential occupancy. Many older buildings of this type are recognized as cultural heritage monuments of national importance due to their significant cultural and historical value. Various methodologies for assessing the seismic risk of such structures have been developed globally and can be used to prioritize the buildings at significant risk of damage or collapse. These buildings would need to be retrofitted to prevent possible human and material losses in future earthquakes.

The goal of the seminar is to present various methodologies for assessing the seismic safety of masonry structures and illustrate their application. The first part of the seminar is focused on the methodology for seismic assessment of masonry buildings developed in New Zealand after the 2011 earthquake, which caused significant damage to masonry structures in the epicentral area of this earthquake, particularly in the city of Christchurch. The presentation will share experience in termos of the earthquake effects on masonry buildings, as well as subsequent changes in the relevant policies, codes, and guidelines. Our invited guest speaker is Jitendra Bothara, who participated in the development of the methodology for seismic assessment of masonry buildings, which has been officially accepted in New Zealand and can be accessed via URL https://www.eq-assess.org.nz/

Second part of the seminar is dedicated to the ADRISEISMIC project (2020-2022) sponsored by the EU’s Interreg program, which dealt with the protection of heritage buildings in the historic city centers from the consequences of damaging earthquakes. Countries in the Adriatic and Ionian Sea region, including Italy, Slovenia, Croatia, Serbia, Albania, and Greece, participated in the project. Members of the Serbian team will present the content and results of this project. The project had three themes, i.e. review of the existing technical regulations related to the protection of cultural monuments from earthquakes (WPT1 work package), development of a methodology for seismic risk assessment and retrofitting techniques for masonry buildings (WPT2 work package), and training programs for professional staff involved in the preservation of urban heritage buildings (WPT3 work package). The ADRISEISMIC methodology for rapid seismic risk assessment of masonry buildings, developed at the University of Bologna (Italy), will be presented at the seminar, along with an example of the application of this methodology to more than 400 buildings in the center of Belgrade.
