2nd Croatian Conference on Earthquake Engineering 2CroCEE

Development of a classification system (taxonomy) for buildings is a critical step for seismic risk assessment studies, and can be used to characterize a building portfolio within urban/rural settlements or building stock for entire country. Serbia is located in a region characterized by a moderate seismic hazard. In the last century, 10 earthquakes of magnitude 5.0 and higher occurred in Serbia, and the strongest earthquake (M 6.0) occurred in 1922. The strongest earthquake in 21st century (Mw 5.5), with epicenter close to Kraljevo, occurred in November 2010 and caused significant damage of residential buildings. In 2019, members of the Serbian Association for Earthquake Engineering (SUZI-SAEE) have contributed to the SERA project which had a goal to develop seismic risk model for Europe. A taxonomy for residential buildings in Serbia has been developed based on the previous studies on national building stock. The proposed taxonomy considers the Lateral Load-Resisting System (e.g., wall, frame, dual wall-frame system) and material of the LLRS (e.g., masonry, concrete, wood) as the main attributes. The type of floor diaphragm (rigid or flexible) has been specified only for masonry typologies with unreinforced masonry walls, and building height and date of construction have been implicitly considered. According to the proposed taxonomy, there are 8 residential building typologies in Serbia; out of those, 4 typologies are related to masonry structures, 3 typologies are related to RC structures, and one is related to wood structures. The paper describes proposed taxonomy and outlines characteristic features of different building typologies and their relevance for estimation of seismic vulnerability and risk. A comparison of the proposed taxonomy for Serbia and published taxonomies for Croatia is also going to be presented.
