abstract / sažetak
Buildings aggregates are part of the typical architecture of the historical City center of Zagreb, along with many other city centers throughout Europe. The earthquake in the City of Zagreb (March 2020), and recent earthquakes in Italy, suggested the interaction of structural units within aggregate, and their complex behavior during earthquakes, including seismic pounding. Literature, current norms, and regulations for this problem still do not provide clear instructions. An overview of experimental and numerical methods from the available literature that analyze the mutual influence of buildings in aggregates regarding the characteristics of the City of Zagreb is presented. The emphasis is on unreinforced masonry structures numerical modeling and retrofitting strategies and interventions for the whole aggregate, and analysis of current engineering practice in Croatia.
Zgrade u blokovima i nizovima dio su tipične arhitekture povijesnog centra grada Zagreba, kao i mnogih središta gradova diljem Europe. Potres u Zagrebu (ožujak 2020.), kao i nedavni potresi u Italiji, ukazali su na međudjelovanje stambenih jedinica i njihovo kompleksno ponašanje pri potresnom djelovanju. Literatura, norme i propisi u ovom dijelu još uvijek ne daju jasne upute. Prikazan je pregled eksperimentalnih i numeričkih metoda iz dostupne literature koji analiziraju međusobni utjecaj zgrada u blokovima s osvrtom na karakteristike grada Zagreba. Naglasak je na numeričkom modeliranju i prijedlogu metoda sanacije i protupotresnog ojačanja blokova kao cjeline, kao i analiza trenutne inženjerske prakse.
