Collapse rates of reinforced concrete structures during large magnitude earthquakes: case study for Romania

Abstract

Highlights The Vrancea earthquake of March 1977 was the most damaging event in Romania in the XXth century; The largest collapse ratio (0.0067) among the analysed structures was observed for RC silos; No collapses were observed for multi-storey industrial buildings and large panels structures; Very small collapse ratios were noticed for residential RC high-rise structures built in the ‘60s and ‘70s
