The collapse and damage of large number of buildings during the November 26,
2019 (Mw 6,4) Albania earthquake caused 51 fatalities and injuries to at least 910
people. Most of collapsed or heavily damaged buildings were RC frame buildings.
Although RC frame system is considered as very ductile seismic force-resisting
system, its behaviour during earthquake highly depends on: (1) regularity in plan
and elevation, and (2) global and local ductility. Based on the authors’ visit to the
earthquake-affected area on behalf of the Serbian Association of Earthquake
Engineering and observations of collapsed and damaged buildings, it was
concluded that among main reasons for underperformance of these flexible systems
were inadequate analysis of interaction between infill walls and RC frames and
reinforcement detailing of RC members
